fix(process): bounds-check GetJavaStacks thread parsing - #630
Merged
Conversation
The jstack parser indexed fields[1] of a thread header line without checking the slice length. A thread name crafted to leave fewer than two trailing fields caused an index-out-of-range panic that crashed the server. Guard the length before indexing. Adds testdata plus a regression case.
