Error description

• Environment:
  - RSA 8.5.1
   - Windows 7
  
  Reproducible: Y
  
  Description of problem:
  
  On some models, when you run a UML-?WSDL transformation, the
  transformation runs for more than 10 minutes and ends up with a
  java.lang.OutOfMemoryError. This only happens when the option to
  convert a nested class to anonymous type implicitly is checked,
  but it occurs even when all types are named.
  
  If you increase the heap size sufficiently, the OutOfMemoryError
  won't happen, but the transformation never finishes.
  
  
  
  Here's an extract of the trace that can be seen in the logs:
  
  !ENTRY org.eclipse.ui 4 0 2013-05-21 11:58:24.556

      at org.eclipse.core.internal.jobs.Worker.run(Unknown Source)
  
  
  Steps to reproduce
  
  1) Create a UML to WSDL transformation
  
  2) Make sure that the option to convert a nested class to
  anonymous type implicitly is checked,
  
  3) Run the transformation.
  
  4) Notice that the transformation takes a lot of time and that
  after 10 to 15 minutes it fails with an OutOfMemoryError.
  
  Workaround
  
  The only workaround is to deactivate the conversion of nested
  classes to anonymous types implicitly, but this is not an
  acceptable solution as it does not generate the desired WSDL.

  UML to WSDL transformation throws OutOfMemory error for
  large models.
  

Problem conclusion

• Running the UML to WSDL transformation executes without and
  OutOfMemory Errors even for large models.
