Problem in MyEclipse "Processing Dirty Regions"

Question

Is there anyone who have encountered "Processing Dirty Regions" error in MyEclipse? Actually everytime i press a key in JSP it shows a popup, which says

An internal error occurred during: "Processing Dirty Regions". org/eclipse/wst/sse/ui/internal/reconcile/validator/ValidationHelper

By googling i found that i have to rename a jar , i did that but what it does is, it will open the JSP in notepad or any other system editor [ now it will not open in MyEclipse]. So this solution is discarded.

Please let me know how to resolve this problem?

Answer 1

Reverting MyEclipse Configurations to earlier version solved this problem.

Help > Software Updates > Manage Configuration

Select 'Revert to previous' now select the configuration you think, was not having the problem.
