Also, I just checked the stack trace you sent against the current uima-core
and cant seem to reconcile the line numbers in the stack trace. It appears
that you may not be running with the latest uima core. Check
....
org.apache.uima.cas.impl.CASImpl.release(CASImpl.java:3568)
....
In the latest code CASImpl.java line 3568 does not appear to be inside
release() method
This to me is an evidence that perhaps you may be running with an older
version of uima core..
Yes, I checked again and found out that I mistakenly updated the machine
with an old version which was build on 24th August. The name of the
folder in the distribution package changed from apache-uima-as to
apache-uima,
during the update I then picked the old apache-uima-as folder.
But I will test again with the head version.
Sorry,
Jörn
