Java Segfault with

[Kees Jan Koster]

Dear Tiernan,

Or encode PNGs, as my code does. :)

Thank you for looking this up for me.

I installed an 8-STABLE with the fix last night. Interestingly, this also resolves a problem where I would see excessive CPU usage on the PNG encoding process. Likely the segfault is related to high CPU usage.

I cannot say for sure that this is the case, though. I did a full world install.
