Some more details to the issue:
Perl script "be_docker_run.pm" that extracts tra.java.extended.properties corrupts the value when a full path added as a reference for the java agent.
e.g.,
Input:
tra.java.extended.properties=-Xms1024m -Xmx1024m -javaagent:/opt/tibco/be/6.2/lib/cep-base.jar
Output:
grep tra.java.extended.properties beprops_all.props
tra.java.extended.properties=/opt/tibco/be/6.2/lib/cep-base.jar -XX:MaxMetaspaceSize=256m
cat /opt/tibco/be/6.2/bin/be-engine.tra
...
tra.java.extended.properties=/opt/tibco/be/6.2/lib/cep-base.jar -XX:MaxMetaspaceSize=256m
Test (same operations as done in /home/tibco/be/run script):
- Connect to running pod
cd /home/tibco/be
CURRENT_DIR=$(pwd)
BE_PROPS_FILE=beprops_all.props
APP_HOME=/opt/tibco/be/application
# set tra.java.extended.properties if not set already
env tra.java.extended.properties="-Xms1024m -Xmx1024m -Xss2m -javaagent:/opt/tibco/be/6.2/lib/cep-base.jar -XX:MaxMetaspaceSize=256m" bash
export PERL5LIB="/home/tibco/be"
perl -Mbe_docker_run -e "be_docker_run::makeBeProps('testSupport.prop','$APP_HOME','$BE_HOME/')"
Result (extracted only values after "-javaagent:")
grep tra.java.extended.properties testSupport.prop
tra.java.extended.properties=/opt/tibco/be/6.2/lib/cep-base.jar -XX:MaxMetaspaceSize=256m
Note:
The property set correctly using %BE_HOME% instead of the full path for cep-base.jar
env tra.java.extended.properties="-Xms1024m -Xmx1024m -Xss2m -javaagent:%BE_HOME%/lib/cep-base.jar -XX:MaxMetaspaceSize=256m" bash
With above settings you able to start an agent when Telemetry not enabled, if enabled the CacheAgent will not start (NullPointer exception).

;tldr
Setting this:
tra.java.extended.properties="-Xms1024m -Xmx1024m -Xss2m -javaagent:/opt/tibco/be/6.2/lib/cep-base.jar -XX:MaxMetaspaceSize=256m"
Results in this being written to the props file:
tra.java.extended.properties=/opt/tibco/be/6.2/lib/cep-base.jar -XX:MaxMetaspaceSize=256m
Whereas, setting:
tra.java.extended.properties="-Xms1024m -Xmx1024m -Xss2m -javaagent:%BE_HOME%/lib/cep-base.jar -XX:MaxMetaspaceSize=256m
Results in this being written to the props file:
tra.java.extended.properties=-Xms1024m -Xmx1024m -javaagent:/opt/tibco/be/6.2/lib/cep-base.jar
