Java Segfault with

[Kees Jan Koster]

Dear Tiernan,

Thank you for the suggested fix. Other than running Minecraft, do you have any way to reproduce this?

Also, can you please dig a little to find where you found this? I'd like to file a bug report for this. If you can't there is no man overboard, but I like to be thorough.
