Hi,
We use to have FishEye in version 2.7.3 but we tried to install the new Fisheye 3.8 (We also tried FishEye 3.8.1), it worked great with Java6 but now that we upgrade to java7 we can't start it anymore .. Even stranger, the fecru-2.7.3 still works well with this JDK, only fecru-3.8+ won't start anymore

... then nothing happens 
Our java version is
java version "1.7.0"
Java(TM) SE Runtime Environment (build pxa6470sr6-20131015_01(SR6))
IBM J9 VM (build 2.6, JRE 1.7.0 Linux amd64-64 Compressed References 20131013_170512 (JIT enabled, AOT enabled)
Sometimes after 15 or 20 minutes (where we can't access at all the server), we can see this :

The config.xml is good as it use to works when the server was running with java 1.6; Do you guys have any ideas on how to debug this issue (no real logs/error or anything..) or fix this ?
