[cdt-dev] reconciler null pointer exception patch
|
This patch prevents a null pointer exception in
org.eclipse.jface.text.reconciler.AbstractReconciler. Under certain
conditions (like rapidly closing all editors) the call to getDocument()
inside initialProcess() can return null which causes an exception.
