Description
dev/random currently is read-only. On other OSs, writing data to it is used for seeding or increasing the entropy. OpenJDK's NativePRNG class uses dev/random writes and will thus throw exceptions on re-seeding. With the attached patch, I'm able to run Netbeans 7.3beta2 with only few problems remaining.

Here you go! Also removed the tracing which was still activated in the last patch.

Patch is acceptable as is, but it seems like C style, whereas the file is C++. This should be improved at a later time.

It is indeed. I've removed the workaround now. Thanks korli, and thanks fishpond for the patch.
