After upgrade, we are getting
JENKINS-18403 JDK 5 not supported to run Maven; retrying with slave Java and setting compile/test properties to point to <PATH>/jrockit-jdk1.6.0_45-R28.2.7-4.1.0
and Java switches to 1.8.0_45
I saw that both 1.594 and 1.642 were compiled against the same java, so why I am getting this message? What change is causing this error?
