Problem

Groundwork currently provides the latest version of Oracle JDK7 (1.7.0u76). While functional, this version may be too old to meet the requirements for certain organizations. Groundwork is unable to update to Oracle JDK8 at this time due to incompatibilities with JBOSS Portal Platform. The OpenJDK-7 has been shown (under certain conditions) to work well with Groundwork and may help these organizations meet their requirements. At this time, Groundwork is unable to provide OpenJDK as an installation option due to various platform-specific dependency conflicts, although this is still under investigation.

Support Considerations

Groundwork is committed to ensuring that customers are able to meet their organizational requirements and we will strive to ensure that OpenJDK will work well for you. With that said, this approach has not been widely tested and is considered a feature that should only be pursued if there are no other good alternatives. At this time, we have conducted basic testing in the following environments and not observed any unexpected behavior:

GW Version	Linux Version	Java Version	Status
7.1.0	Ubuntu 14.04	OpenJDK 1.7.0_121	Pass
7.1.1	Ubuntu 14.04	OpenJDK 1.7.0_121	Pass

7.1.0	RHEL 7	OpenJDK 1.7.0_121	Pass
7.1.1	RHEL 7	OpenJDK 1.7.0_121	Pass

In depth testing of various features with complex configuration scenarios are in progress but have yet to result in any failures or other system issues.

Solution

TB 7.1.1-2 provides the changes necessary to a Groundwork 7.1.0 or 7.1.1 installation to use a separately installed JDK7 such as OpenJDK 1.7.0_121.

Installing

Install desired JDK7 (e.g., OpenJDK 1.7.0_121)

Download and run the install script:

Note for SSL:

For systems with SSL enabled following the procedures in the SSL Doc, the following change is necessary for this Technical Bulletin:

Step 15 calls for the following command:

keytool -import -file /usr/local/groundwork/apache2/conf/server.crt -alias myserver.mydomain.com -keystore /usr/local/groundwork/java/jre/lib/security/cacerts

The "/usr/local/groundwork/java" portion of the last argument must be changed to the location of the version of Java selected as a part of the Technical Bulletin installation.

Ex:

keytool -import -file /usr/local/groundwork/apache2/conf/server.crt -alias myserver.mydomain.com -keystore /usr/lib/jvm/java-7-openjdk-amd64/jre/lib/security/cacerts

where, "/usr/lib/jvm/java-7-openjdk-amd64/" is the new java path.

Make this change when enabling SSL as a part of that defined procedure, or execute this updated command on a system with SSL already enabled prior to installation of the Technical Bulletin

If 'java' is not a typo you can use command-not-found to lookup the package that contains it, like this:

===== Groundwork Patch 7.1.1-2 installer =====
This patch will allow you to have Groundwork use a
custom installed JDK7 instead of the included Oracle JDK7.
Please note that this script will stop/start Groundwork which
will result in a few minutes of downtime.

Uninstalling

Download and run the uninstall script:

Name	Size	Creator	Creation Date	Comment
TB7.1.1-2_uninstall	2 kB	Ryan Graffy	Feb 10, 2017 08:16	Updated for GWMON-12884

Note that the uninstaller restores the use in GroundWork of the bundled Java 1.7. It does not uninstall the version of Java 1.7 121 or other that you placed into the operating system. Thus once the uninstaller has run you will have the system back to native GroundWork consistency. The log file in the common/var/patches directory contains the record of all installs and uninstalls as you do them.
