private static boolean transformClass(WovenClass wovenClass, ClassLoader cl, ClassTransformer transformer)
  throws ThreadDeath, OutOfMemoryError {
  try {
    byte[] result = transformer
      .transform(cl, 
            wovenClass.getClassName(),
            wovenClass.getDefinedClass(), 
            wovenClass.getProtectionDomain(),
            wovenClass.getBytes());
    if (result != null) {
      wovenClass.setBytes(result);
      wovenClass.getDynamicImports().add("org.eclipse.persistence.*");
      wovenClass.getDynamicImports().add("org.apache.openjpa.*");
      return true;
    }
  } catch (Exception t) {
    Bundle b = wovenClass.getBundleWiring().getBundle();
    String msg = String.format("Weaving failure on class %s in bundle %s/%s using transformer %s", wovenClass.getClassName(),
                  b.getSymbolicName(), b.getVersion(), transformer);
    throw new WeavingException(msg, t);
  }
  return false;
}
