+++ This bug was initially created as a clone of Bug #325464 +++

STEPS:
1. create a SWP
2. create a JS file using the new JS file wizard
3. add a single double quote to the document (syntax error)

RESULTS:
1. without saving the document the syntax validation error should be reported by its not

CAUSE:
this is because in NewJSFileWizardPage@#addFileComment the line: "cu.becomeWorkingCopy(new NullProgressMonitor());" (added by Bug 268125)

This causes the working copy to be created without a problem requester. Then when CompilationUnitDocumentProvider#createFileInfo is called there is a bit of code that reads:
/*
* Use the deprecated method to ensure that our problem requestor is
* used; it is the only way to have as-you-type IProblems from
* reconciling appear in the annotation model.
*/
if (JavaModelUtil.isPrimary(original))
  original.becomeWorkingCopy(requestor, getProgressMonitor());

This attempts to set up the working copy again using the correct requestor, problem is in CompilationUnit#becomeWorkingCopy(IProblemRequestor, IProgressMonitor) if the PerWorkignCopyInfo already exists then nothing is done.
