Hi Jukka, we cannot simply replace the option, since it's unknown to Java 7:
> java -version java version "1.7.0_72" Java(TM) SE Runtime Environment (build 1.7.0_72-b14) Java HotSpot(TM) 64-Bit Server VM (build 24.72-b04, mixed mode) > java -jar -XX:MaxMetaspaceSize=128m ... Unrecognized VM option 'MaxMetaspaceSize=128m' To avoid the warning we'd have to first recognize the java version, and then decide which option to use (or if you to use it at all). It's probably not too hard I guess, we'd have to parse the first line of output in "java -version", extract the version and setup the options accordingly. But wondering if we should just leave it be and wait for us to upgrade to java 8 as the minimum version. On one side, java 7 is unsupported, on the other end, we have enforced java 7 only recently (starting with 2.6.x if I remember correctly), so not sure 2.8.x will be a good time to do the switch... maybe 2.9.x instead? (March 2016?)
