  Local fix:
  
  Turn off automatic build before creating or importing a project
  via Project ? Automatically.
  
  Once the project exists, you can right-click on the project,
  select Properties ? Builder and un-select the JavaScript
  Validator builder. Turn on automatic build afterwards.
  

Local fix

Problem summary

• The JavaScript builder/validator was hanging due to an infinite
  loop when validating the code.
  

Problem conclusion

• A check was put into the code to avoid duplicate checks and
  eliminate the infinite loop.
  
  The fix for this APAR is included in Rational Application
  Developer v8.0.4.3.
  

Temporary fix
