What is the expected behavior?

IA starts without NPE when configured with Open Telemetry OTLP type

What is the actual behavior?

NPE thrown and IA fails

Please provide a unit test that demonstrates the bug.

Other notes on how to reproduce the issue?

When tra.java.extended.property is set via environment through Helm chart and it contains hard coded path to the cep-base.jar rather than %BE_HOME% then the perl script generates incorrect value for tra.java.extended.properties with the value of the javaagent property missing.

Please provide log files.

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).

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
