intellisense in eclipse error

I use Eclipse

Version: 3.4.2 Build id: M20090211-1700 The problem I have is that when i use intellisense the error pops out

Problems During Content Assist The org.eclipse.jdt.ui.java.TypeCompletionProposalComputer' plug开发者_开发问答-in did not complete normally. The execution took too long to return from computeContextInformation() operation

Is there a fix for it?

thanks

Check, in Window > Preferences > Java > Editor > Content Assist > Advanced if there is any unusual item checked. Only let Java and Template proposals checked and apply... Maybe it could be 'cause of one of the other code completion tools.
