Is OpenJDK supported with RTC Client/scmtools 6.0.1?

I am setting up a Maven Build continuous integration environment, and one problem we have found is that when we are building our maven projects using OpenJDK and SCMTOOLS 6.0.1, when we perform "Maven Release Cycle" (mvn release:prepare release:perfrom), we get the following error:

12:19:32 [DEBUG] ErrorConsumer.consumeLine: -vm /usr/lib/jvm/java-1.8.0-openjdk.x86_64/bin/java
12:19:32 [DEBUG] ErrorConsumer.consumeLine: -vmargs

12:19:32 [ERROR] Error: Unrecognized option: -Xshareclasses:nonfatal


We do not get this error if we use RTC 4.0.6 or if we use IBM JDK. This leads me to believe that there is something that was introduced in 6.0.1 that perhaps requires IBM JDK.
I am not finding any documentation for the parameter "-Xshareclasses:nonfatal" existing in openJDK, while it clearly is documented in IBM JDK.
It is not a parameter that we specify, it is being generated by the scmtools.

If this is a known issue, or if OpenJDK is not supported can you please point me to the documentation?

Thanks,
James Murphy

You have to edit out the IBM jvm only parms from the eclipse profile

Thank you! Didn't know where to look to be able to comment out those options, finally found it in the file "scmtools/eclipse/scm.ini"
