  • 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
