[webkit-dev] DumpRenderTree crashes because of JavaPluginCocoa

[Xianzhu Wang]

Hi,

I encountered a problem yesterday that all layout tests crashed on Mac Snow
Leopard.

DumpRenderTree produces the following output when run from command line:

$ time ./DumpRenderTree

(/System/Library/Frameworks/JavaVM.framework/Versions/1.6.0/Home) cannot be
loaded on this system. Using CurrentJDK instead.

===============================

I tried to remove /Library/Internet Plug-Ins/JavaPluginCocoa.bundle, then
DumpRenderTree worked.

Anyone has encountered the same problem and/or has better solution?

BTW, why is crash reporting for DumpRenderTree so slow (3.5 minutes)?

Thanks,
Xianzhu
