I managed to fix the problem. First of all you will have to edit file SIPtestsGlobal.jmx that is placed in simulap-plugin-sip/tests and replace all text occurens from org.apache.jmeter to com.hpe.simulap,, there is something like 1,2k of changes to be made in this file, Then you will also have to place this library:
https://mvnrepository.com/artifact/javax.xml.bind/jaxb-api/2.2.9
in $JMETER_HOME/lib. After this changes it should work.

Please insert into JMeter's bin/upgrade.properties file, the content of bin/upgrade.properties.sip to solves the issue.

Had some issues getting it to run, but this finally worked for me:

• As @Pancor said, replace all occurrences of org.apache.jmeter with com.hpe.simulap in simulap-plugin-sip/tests/SIPtestsGlobal.jmx
• Make sure to use Java 8
• Copy JAXB API jar file into JMETER_HOME/libexec/lib/ directory (using jMeter 5.4.3)

Please insert into JMeter's bin/upgrade.properties file, the content of bin/upgrade.properties.sip to solves the issue.

This didn't work for me, I had to manually replace names in the test plan file.
