logger conversionPattern restriction doesn't work correctly for Generic classes

<conversionPattern value="%date %-5level %logger

- %message%newline"/>

Using the above conversion pattern for a logger of a Generic class (i.e. My.System.MyClass<My.System.MyObject>) will result in the following log output:

2008-01-17 21:54:48,968 INFO 0, Culture=neutral, PublicKeyToken=null]] - My error message

Obviously, in this case it's not appropriate to just take the portion of the class name after the last '.' character.

Thanks
