HardDeadlineExceededError due to PluginClassLoader

[GoogleCodeExporter]

What steps will reproduce the problem?

I am unsure about the steps to reproduce.  The self registration plugin is 
causing errors.

I installed the self registration plugin and it worked correctly for two weeks, 
however now I am getting the following errors for any admin activity I try in 
the admin console.  E.g., this error occurs when looking at the Content section 
of the admin console.

It seems that the PluginClassLoader continues to try and create the 'register' 
class loader but eventually hits the GAE hard deadline exception.  Any help 
would be greatly appreciate.  I am unable to uninstall the register plugin 
because I can't open the list of plugins in the admin console.  Other plugins 
such as the Atom RSS plugin do load correctly.

UPDATE:  I cleared the cache by going to URL /_ah/reset_cache and now the 
PluginClassLoader is working correctly and the error is not occurring any more.
