Reload loop after login

[useher]

Hello!

With a system-upgrade (openSuse 42.2 ->42.3->15) my tomcat-server is upgraded to version 9, the underlying JRE switsched from oracle to OpenJDK. The jasperserver-ce-app starts fine, but after login a reload-loop starts, which cannot be stopped, so the app is unusable.  The directory is shown, but no folder can be opened. Other apps work like before. The logfile do not show anything i can handle. Some lines are attached below, more can be delivered if needed.

So how can i stop this behavior.

Thank you in advance

Hello again!

So if this is an issue when th jvm has changed i tried to change the JAVA_OPTS in the way described in the documentation:

CATALINA_OPTS = "-Xms1024m -Xmx24576m -XX:PermSize=2048m -XX:MaxPermSize=4096m -XX:+UseConcMarkSweepGC -XX:+CMSClassUnloadingEnabled"

This works but has no effect on jasperserver. So if someone has solves this problem, please tell me how.

A short comprehension: openSuse LEAP 15, java 1.8, jre changed from oracle to openJDK, tomcat updated from 8 to 9, other applications ran as normal.

Thank you in advance
