IV22692: CORE FILE NOT FOUND IF CORE_PATTERN CONTAINS %E

APAR status

• Closed as program error.

Error description

• Error Message: When creating a system dump, the Java VM prints a
  message like:
      The core file created by child process with pid = 3590 was
  not found. Expected to find core file with name
  "/home/jdoe/core_java.3590"
  .
  Stack Trace: N/A
  .
  Also, the JVM does not print a message like:
      JVMDUMP010I System dump written to /home/jdoe/core_java.3590
  

Local fix

• Remove %e from core_format.
  

Problem summary

• Core file not found if core_pattern contains %e
     Linux expands %e to the thread name, not the process name.
  This affects only Java 7 and Java 6.0.1 running on Linux.
  

Problem conclusion

• This defect will be fixed in:
  6.0.1 SR2 FP1
  7.0.0 SR2
  .
     The JVM dump processing has been changed to use the thread
  name instead of the process name to locate the core file.
  

Temporary fix
