Heya, I just pulled the commits by Abhinandan Prateek into master. With the switch to java 7 on master we need ire 7 in the systemvms. If you are testing with master be sure to download the latest systemvm builds (after commit id d578d7ef85a7304aec18a207a35535f62eed0e0b). Otherwise starting the secondary storage vm will fail because of incompatible class versions.
The latests builds are available here: http://jenkins.buildacloud.org/job/build-systemvm-master, build 77 and up have the ire 7. Cheers, Hugo
