ISCFile.lastModified NullPointerException

fyi,
I thought to try the latest 9/05/2011 build, but it doesn't startup:

[Isomorphic]

The first seems to indicate the Init servlet has not been run, and the second indicates bad <inherits>. Check the Troubleshooting section at the end of the installation procedure, both are mentioned.

Tried with the 14/05/2011 build (upgrading from 2/05/2011) and same error occurred (never had it before on an upgrade).

Restarting Eclipse was the magic trick. The project works again.
