Not able to Start JasperStudio

[acox]

I'm getting the following errorlog when trying to open Studio.   This started happening after an upgrade to Java 8 71, coincidence?

Finally found a solution which has nothing to do with Java or Eclipse.  
Delete the ..JaspersoftWorkspace/.metadata folder and re-start Studio.
