Ok with Java 1.7
Hi
we have now switched to Java 1.7 and it's working.
The hidden fields are now also hidden in the mobile view.
Great work!

OK, I see. Starting from JIRA
OK, I see. Starting from JIRA 6.0, the only supported JDK version is 1.7 (https://confluence.atlassian.com/display/JIRA060/Supported+Platforms), so JFS 1.4.22 for JIRA 6.0-6.2 has been recompiled with JDK 1.7, hence the error.
Could you switch to JDK 1.7 on your production JIRA instance?
