Array not zeroed on creation (original) (raw)

Dan,

I've cc'd compiler dev and removed hotspot dev as this looks like a compiler issue. Hope you don't mind.

My hunch is that the Arrays.fill() is tripping this up - is it reproducable if fill() is removed?

Basically there is a reproducible (by several people) situation where a new int array is not zeroed. The author reports the error is reproducible on HotSpot 64-bit server VM, Java version from 1.7.004 to 1.7.010 on Gentoo Linux, Debian Linux (both kernel 3.0 version) and MacOS Lion. (Not tested on 32-bit or Windows.) Reportedly bug7196857 has been filed with Oracle. -- Dan Hicks Nothing makes us so lonely as our secrets. --Paul Tournier -------------- next part -------------- An HTML attachment was scrubbed...
