Error description

  • Error Message: N/A
    .
    Stack Trace: N/A
    .
    When analyzing a system dump from a JVM on Windows 32-bit, the
    jdmpview 'info thread' command fails to print a complete native
    stack trace. For example:
       native stack frames:
        bp: 0x548cdf5c pc: 0x7c91e4f4
    C:\WINDOWS\system32\ntdll.dll::KiFastSystemCallRet+0x0
        bp: 0x548cdf70 pc: 0x7c802542
    C:\WINDOWS\system32\kernel32.dll::WaitForSingleObject+0x12
        bp: 0x7fa61ad0 pc: 0x7edf8d5c
    C:\Programme\IBM\SDP\jdk\jre\bin\default\j9prt26.dll::<OSB>dump_
    create<CSB>+0x1fc
    

Local fix

  • Use windbg with the SDK libraries and .pdb files to obtain more
    complete native stack traces from the system dump.
    

Problem summary

  • The problem is caused by compiler optimisations which remove
    information needed to print complete native stacks.
    

Problem conclusion

  • This defect will be fixed in:
    7.0.0 SR6
    6.0.1 SR7
    .
    The Windows 32-bit JVM has been updated to allow jdmpview to
    print more complete native stacks.
