Null Pointer Exception when creating new model or reimport a model

Issue

I'm trying to create or import a model, I find this error below.

I am using SAP NetWeaver Developer Studio 7.0, apparently there is some incompatibility of some java plug-in for this platform to be run on Windows 7.

Any help!?

An internal error has ocurred. See error log for more details.

Solution

The Null pointer Exception throws when some variable doesn't have any initial values. Restart the application may force the program work fine.
