Subject RE: Headstart on "Resolving OOM-PermGen errors on webapp reload"
Date Wed, 22 Apr 2009 18:05:05 GMT
I don't doubt that jmap/jhat would be able to give you more detailed information.  My exact
goal was to come up with something for automated testing that would help prevent classloader
leaks from making it into production.  If someone can think of a programmatic way to do that
with jmap/jhat, please share!

Other than being programmable for automated testing purposes, does this provide any more or
different information than a jmap/jhat combo?
