This morning I noticed the following stacktrace starting TomEE on my laptop:

----------------------
Looking at some of the bug reports about this, for instance
https://bugs.eclipse.org/bugs/show_bug.cgi?id=193269 , it appears that it's
essentially a flaw in Inflater (although the Oracle reference appears to say
this had been fixed), but that it's possible to implement a workaround in user
code.
As my Google search for this found it referenced in several frameworks, but not
Tomcat or TomEE, I'm guessing this has not been reported here before (seems
hard to believe). The "user code" appears to be in Catalina, according to the
stacktrace.
