--- Comment #7 from Mark Thomas <ma...@apache.org> ---
I've dropped the sleep to zero and I still haven't seen this error. I have seen
various other similar errors though.
There are likely to be many, many code paths that will trigger different
exceptions. In each case the first indication of a problem is the following log
message:
01-May-2020 17:39:34.570 WARNING [Thread-4]
org.apache.catalina.loader.WebappClassLoaderBase.clearReferencesThreads The web
application [tomcat-bugs] appears to have started a thread named [Thread-5] but
has failed to stop it. This is very likely to create a memory leak. Stack trace
of thread:
Note that the name of the thread that has not been stopped is given in the
above message.
What then follows is:
Exception in thread "Thread-5" ...<1 of various exceptions>
Note that the various exceptions will occur on the thread that hasn't been
stopped. Therefore, I consider the first warning message sufficient explanation
for the following exception(s). I do not think that the effort required to
provide "better" messages in those cases is justified as determining the
current state so the "right" "better" error message can be displayed will be
complex and - in some cases - may not be possible.
Therefore, I do not intend to fix this issue.
