From time to time I also have a crash in java.util.zip.ZipFile.getNextEntry
(linux-amd64 is in use) - regardless Eclipse. Have not noticed any regularity.
Both with Sun JDK and OpenJDK. But it seems with GTK L&F it is more frequent
rather with Nimbus one.

That does look like a library combination bug, but hard to tell. If it's
not in the Sun database, maybe you should submit it to them and see what
they say.

Best,

I've not see it. You should check against Sun's bug database and report it.

As a workaround, you could try using the server compiler rather than the client.

Cheers,

I've already looked, and all what I can find is about Jars changed when
used (for ex: http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6236070)

Perhaps it's something like that involved, with maven updating things,
Scala plugin indexing others, and caches somewhere in Eclipse... Really
hard to tell, I didn't find any reproducible way of making it happens,
and I don't see it in simple projects :/ But when it happens, sometimes
it happens three or four time in a row.

Launching eclipse with -clean seems to help, but not sure it's linked.

I will try to find more information, at least the thread is here if
other people meet this error.
