Since 2.3 the SonarQube plugin does not save the JDK I configure in the SonarQube Post-build Action. Every time I enter the jobs configuration it defaults back to (Inherit From Job).
My job needs a 32bit VM so I am stuck with 1g max for Sonar which fails with OutOfMemory most of the time.
Worked fine with 2.2.1. Unfortunately that does not seem to work well with Sonar 5.2 and sonar-gerrit-plugin 2.2.1 (it won't report back to gerrit).
