[news.eclipse.tools.gef] Re: Exception in thubnail generation for outlin

[vijay.rajonline@xxxxxxxxx (vijay )]

For slow performance of zoom i found the problem,
the problem was shortestpathrouter this router makes zooming scrolling and 
loading also slow,
There is a hack in logic example for using shortestpathrouter but it 
doesnt help in my case,

The exception is still coming any suggestions??
