PK76203: NullPointerException in BundleLoader when Application Client lau nches a multithreaded application

Rational Application Developer for WebSphere Software, Version 7.5.2

APAR status

• Closed as program error.

Error description

• When launching an Application Client configuration from  Rationa
  l Application Developer or Rational Software Architect for WebSp
  here 7 or 7.5, targeting WebSphere Application Server v. 6.1 or
  7, you may get a NullPointerException in an OSGI BundleLoader me
  thod, even if the same Application Client can be launched succes
  fully using the launchClient.bat batch file provided by WebSpher
  e Application Server. This only occurs when the Application Clie
  nt launches a multithreaded application, and typically happens i
  f you are invoking a framework such as JUnit or Swing.
   You see errors like the following in the Console:

  Workarounds:
  
  A. Make the main thread wait for termination of all other user t
  hreads.
  B. Launch the Application Client using launchClient.bat, provide
  d that you have already upgraded WebSphere Application Server v6
  .1 to version 6.1.0.9 or higher.
  C. Use the VM Argument-Dosgi.noShutdown=true in the Application
  Client launch configuration, Arguments tab and make sure that yo
  ur application invokes System.exit.
