Fix your app so that it releases the locks (probably synchronized
sections) on the SimpleDateFormat objects.
Read the stack trace more carefully - only Tomcat or JRE code is present.
However, since this is only a partial stack trace, there might be some app code
that is indirectly locking 0x00007ff9996d4000 and then pausing for some reason,
causing a deadlock.
Hmmm, actually I had a short look at the code of
sun.util.resources.TimeZoneNames.getContents(TimeZoneNames.java:185)
and i don't unerstand why it is waiting for a monitor entry. The method
should quickly return an array of objects which is explicitely defined
in the class and that's it. No idea what's happening here.
@Violeta: is anything wrong with your system, e.g. did you get an
OutOfMemoryError somewhere? It looks your JVM is in a strange state. Are
you doing frequent redeployments without stopping Tomcat?

Rainer
