https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D211196 Bug ID: 211196 Summary: java/openjdk8: thread id missing from jstack output against core files Product: Ports & Packages Version: Latest Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: Individual Port(s) Assignee: java@FreeBSD.org Reporter: ronald.roskens@gmail.com Assignee: java@FreeBSD.org Flags: maintainer-feedback?(java@FreeBSD.org) Created attachment 172643 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D172643&action= =3Dedit patch for hotspot/src/os/bsd/vm/os_bsd.cpp When analyzing a JVM core dump, jstack is unable to display any stacktraces= for any threads because it cannot match any thread id's. In the JVM on BSD, a thread is represented by two different thread id value= s, however, only when defined(__APPLE__) does the second value, unique_thread_= id, get set. Its unique_thread_id that jstack uses to match thread ids in a core dump. I've been using the attached two local patches. patch-rjr-os_bsd.cpp sets unique_thread_id to the same value as the thread_= id. patch-rjr-BsdThread.java adds the unique_thread_id to BsdThread.toString() output. --=20 You are receiving this mail because: You are the assignee for the bug.=
