      Description


      Customer's weblogic based application crashes with the following error
      using debug jdk 1.3.1_03, in native awt font code:
      An unexpected exception has been detected in native code outside the VM.
      Unexpected Signal : 11 occurred at PC=0x844849ec
      Function name=__1cUCompositeGlyphMapperTgetMissingGlyphCode6kM_i_
      Library=/apps/opt/jdk131/jre/lib/sparc/libfontmanager_g.so
      ** complete error and java stack is in the attachment:
      javag_core_othinfo.gz

      The dbx stack snippet (from debug jdk 1.3.1_03) is as follows:
        ---- called from signal handler with signal 11 (SIGSEGV) ------

      ** complete dbx stack and the core file from Sun4u E4500/E5500 is in attached file:
      javag_core_othinfo.gz

      We have seen similar stack traces as above using non-debug jvm and the info is
      saved in the attached file: java_core_othinfo.gz (core is from Sun4u E4500/E5500)
      This part of the test run also contains truss output.

      Unfortunately, this problem is only reproducible (at will) on their production
      environment and not on their staging/qa/dev environments. Unfortunately there
      is no test case which reproduces exact same problem.

      We have collected other info to rule out a font corruption problem, etc,
      saved this info as part of attached file showrev_pkgchk_othrinfo.gz:
      - captured truss output (as stated above)
      - showrev -p output
      Customer is using pretty recent version of Xserver patch 108652-53
      (current rev is at -55)
      - Package check info of all font packages on the system
      - Customer does not have LANG env variable set, neither does he have
      any LC_* variables set (not sure about the impact of this)
      - Unfortunatley we couldn't get "xset -q" output (but they claim not to
      change the default fontpath as such)
