Memory leak in jdk.javadoc.internal.doclets.toolkit.WorkArounds

[Florian Weimer]

It seems that it's currently very difficult to use the javadoc tool in
a long-running VM because there is a severe memory leak.

This appears to be related to the class
jdk.javadoc.internal.doclets.toolkit.WorkArounds, specifically the
field serializedForms.  It looks like elements are never removed from
this map.  Furthermore, even if compiling the same sources over and
over again, existing entries are not reused.

Does this field have to be static?  What's the purpose of this
construct, anyway?  Is it more than just a cache?
