Re: [equinox-dev] Equinox leaking file descriptors

> I do not believe this is related to bug https://bugs.eclipse.org/bugs/show_bug.cgi?id=349121 since David Williams has tried that patch. Also there seems to be issues even on restart for which the SignatureBlockProcessor should not be run.

yeah - we are pretty sure its the ZipEntry/ZipBundle combo "resource handle" we are seeing.

I'll ask snjezana to add our findings to bug 349121
