Description:	JRebel is a plug-in for a Java Virtual Machine (JVM) that enables updates to compile Java class files on the fly or as the Java application is executing. JRebel maps the project workspace in a Java Integrated Development Environment (IDE) directly to the environment where the application is running, skipping the build and redeploy phases. JRebel integrates with the JVM and application servers mainly on the class loader level. This technology does not create any new class loaders, instead, it extends the existing ones with the ability to manage reloaded classes. This technology can reload changes made to a class structure, making a full application redeploy unnecessary. This technology works with many cloud providers. It uses the same port as the application and supports encrypting the connection for public clouds. The TRM decisions in this entry only apply to technologies and versions owned, operated, managed, patched, and version-controlled by VA. This includes technologies deployed as software installations on VMs within VA-controlled cloud environments (e.g. VA Enterprise Cloud (VAEC)). Cloud services provided by the VAEC, which are listed in the VAEC Service Catalog, and those controlled and managed by an external Cloud Service Provider (i.e. SaaS) are not in the purview of the TRM. For more information on the use of cloud services and cloud-based products within VA, including VA private clouds, please see the Enterprise Cloud Solutions Office (ECSO) Portal at: https://dvagov.sharepoint.com/sites/OITECSO This technology can use Oracle database to store data.
Technology/Standard Usage Requirements:	Users must ensure their use of this technology/standard is consistent with VA policies and standards, including, but not limited to, VA Handbooks 6102 and 6500; VA Directives 6004, 6513, and 6517; and National Institute of Standards and Technology (NIST) standards, including Federal Information Processing Standards (FIPS). Users must ensure sensitive data is properly protected in compliance with all VA regulations. Prior to use of this technology, users should check with their supervisor, Information Security Officer (ISO), Facility Chief Information Officer (CIO), or local Office of Information and Technology (OI&T) representative to ensure that all actions are consistent with current VA policies and procedures prior to implementation.
Section 508 Information:	This technology has not been assessed by the Section 508 Office. The Implementer of this technology has the responsibility to ensure the version deployed is 508-compliant. Section 508 compliance may be reviewed by the Section 508 Office and appropriate remedial action required if necessary. For additional information or assistance regarding Section 508, please contact the Section 508 Office at Section508@va.gov.

The VA Decision Matrix displays the current and future VA IT position regarding different releases of a TRM entry. These decisions are based upon the best information available as of the most current date. The consumer of this information has the responsibility to consult the organizations responsible for the desktop, testing, and/or production environments to ensure that the target version of the technology will be supported. Any major.minor version that is not listed in the VA Decision Matrix is considered unapproved for use.

Legend:

White	Approved: The technology/standard has been approved for use.
Yellow	Approved w/Constraints: The technology/standard can be used within the specified constraints located below the decision matrix in the footnote[1] and on the General tab.
Gray	Unapproved: This technology or standard can be used only if a POA&M review is conducted and signed by the Authorizing Official Designated Representative (AODR) as designated by the Authorizing Official (AO) or designee and based upon a recommendation from the POA&M Compliance Enforcement, has been granted to the project team or organization that wishes to use the technology.
Orange	Divest: VA has decided to divest itself on the use of the technology/standard. As a result, all projects currently utilizing the technology/standard must plan to eliminate their use of the technology/standard. Additional information on when the entry is projected to become unapproved may be found on the Decision tab for the specific entry.
Black	Prohibited: The technology/standard is not (currently) permitted to be used under any circumstances.
Blue	Planning/Evaluation Constraint:The period of time this technology is currently being evaluated, reviewed, and tested in controlled environments. Use of this technology is strictly controlled and not available for use within the general population. If a customer would like to use this technology, please work with your local or Regional OI&T office and contact the appropriate evaluation office displayed in the notes below the decision matrix. The Local or Regional OI&T office should submit an inquiry to the TRM if they require further assistance or if the evaluating office is not listed in the notes below.

Release/Version Information:

VA decisions for specific versions may include a ‘.x’ wildcard, which denotes a decision that pertains to a range of multiple versions.

For example, a technology approved with a decision for 7.x would cover any version of 7.(Anything) - 7.(Anything). However, a 7.4.x decision would cover any version of 7.4.(Anything), but would not cover any version of 7.5.x or 7.6.x on the TRM.

VA decisions for specific versions may include ‘+’ symbols; which denotes that the decision for the version specified also includes versions greater than what is specified but is not to exceed or affect previous decimal places.

For example, a technology approved with a decision for 12.6.4+ would cover any version that is greater than 12.6.4, but would not exceed the .6 decimal ie: 12.6.401 is ok, 12.6.5 is ok, 12.6.9 is ok, however 12.7.0 or 13.0 is not.

General Analysis

Adoption Benefits

At the time of writing, no National Institute of Standards and Technology (NIST) vulnerabilities had been reported and no VA Cyber Security Operations Center (CSOC) bulletins had been issued for the latest versions of this technology.
This technology has a comprehensive set of documentations.

Adoption Risks

The technology requires the purchase of licenses from vendor, which could potentially lead to vendor lock-in.
System scans indicate that this technology is no longer in use within the VA network.
This technology has a free trial period, which carries the potential for the disruption of service delivery and inaccurate financial planning.
Due to the frequency of this technology`s updates, the VA may be unable to keep up with the rapid release schedule of this technology and may require a usage model that requires specific versions.
This technology can be implemented with Kubernetes. At the time of writing, Kubernetes is limited to on premises VA Enterprise Cloud implementations on Amazon Web Services (AWS) Servers. Other uses of this technology are unapproved.
This technology can potentially use Jetty, OpenJDK, Docker Compose, Grails, Google Web Toolkit (GWT), Cloud Foundry Command Line Interface (CLI), Eclipse Temurin, unapproved technologies.
This technology is available as freeware. If commercial support is not purchased, the product will be without clearly defined support options which may result in suboptimal enterprise level support.
This technology relies on Java Development Kit (JDK) - Oracle, which has a rapid release and update schedule.

Architectural Benefits

This technology is portable as it runs on multiple TRM-approved operating systems.
This technology integrates with multiple frameworks, application servers and integrated development environments.
This technology is compatible with virtual machines, therefore consistent with the enterprise Server Virtualize First Policy (VAIQ 7266972 08-27-2012).
This technology can use a VA-preferred database.

Architectural Risks

This technology enables Java code to be changed on a production system without formally following change management and configuration management processes, and without re-deploying the code to production through test and deployment stages.
This technology includes cloud-based functionality which has potential information security risks.
