Solve the Problem of errors running builder JavaScript validator in eclipse-Helios)

The latest version of eclipse-jee-helios-win32.zip has not been changed in use, that is, when a previous web project is opened, an error always pops up during verification:
Errors occurred during the build.
Errors running builder 'javascript validator' on project '##'.
Java. Lang. nullpointerexception
To solve this problem, remove JavaScript validator. The removal method is: Right-click a project -- Right-click Properties -- Builders (two in the row) -- click right and there will be four items -- cancel the check box of the first JavaScript validator item and it will be OK.
