This looks like a compiler/GC bug. Try building fastdebug, maybe it shall assert meaningfully? Also, si_addr is probably meaningful.

This is suspicious, because it looks like the double-fault during reporting the original error. Looks as if the arrayOop at 0x7a030ce80 is bad -- and maybe that is the reason why C1-compiled Java code failed?
