Subject JVM crash after groovy 2.4.6 upgrade
Date Mon, 30 May 2016 11:27:13 GMT
This is a little stab in the dark, but we are seeing JVM crashes (at least 10 so far, so it
isn't a fluke) after a recent groovy 2.4.5 -> 2.4.6 upgrade.

The crash happens here [] ZIP_GetEntry+0x11a which appears to be triggered
by groovy invoking the class loader to compile something.

Full details here:

The closest openJDK bug reports I could find are caused by something trying to change the
contents of a zip while it is open. Because I haven't yet figured how to make the JVM crash
on demand, I haven't been able to pinpoint this. And as you can see, my code involves JasperReports
invoking Groovy and there is quite a lot going on.

But I thought I'd give it a shot: has anyone seen something similar? Is this likely to be
related to the upgrade of groovy?
