James Perkins commented on WFCORE-4115:
---------------------------------------

I honestly have never looked at JDK 8 GC logs and barely JDK 11 logs now :) I think we need someone from GSS to give a review as they are the ones that use these the most. [~bmaxwell] is there someone that can look at this? There's likely nothing we can do and just using the Java 11 tools instead of Java 8 tools should likely work.

> * Weird naming of gc log files
> ** I test this with JDK11
> ** I start standalone and stop standalone
> ** JDK10 creates JBOSS_HOME/standalone/log/gc.log (with detailed information) and JBOSS_HOME/standalone/log/gc.log.0 (with brief summary of gc logging)
> ** I start standalone and stop standalone again
> ** JDK10 moves original gc.log to gc.log.1
> ** JDK10 keep original gc.log.0
> ** JDK10 creates new gc.log (with detailed information) and gc.log.2 (with brief summary of gc logging)
> ** Can this be changed by GC settings?
> * GC logs are much more verbose against jdk8 gc logs. Can this be fixed by some JDK10 gc settings? 
> This is follow up for WFCORE-3996
