IV21472: INABILITY TO USE ATTACH API ON A JAVA PROGRAM RUNNING AS A WINDO WS SERVICE ON WINDOWS 7

APAR status

• Closed as program error.

Error description

• Error Message: When a Java program running as a Windows user
  process tries to use the Attach API to connect to a Java program
  running as a Windows 7 service, either the service process is
  absent from the output of AttachProvider.listVirtualMachines()
  or the attach attempt fails after a long delay.
  .
  Stack Trace: N/A
  .
  

Local fix

• A process running as a service can attach to other Java services
  owned by the same user.
  

Problem summary

• User processes cannot attach to services and vice versa due to
  Windows operating system restrictions. Inter-user permission
  failures can cause corruption of the service's files for attach
  API. This does not affect other aspects of the service process's
  operation.
  

Problem conclusion

• This defect will be fixed in:
  7.0.0 SR2
  6.0.1 SR3
  6.0.0 SR11
  .
  The JVM has been fixed to prevent corruption or removal of
  Attach API files for processes owned by other users. Attachment
  between user processes and services is not supported; an
  "AttachNotSupportedException" is thrown if a user process tries
  to connect to a Java service.
  

Temporary fix
