Apache Sling Request Parameter Handling Bug - NullPointerException

Hi,

I'm using Adobe Experience Manager, Version 6.0.0.SP1 and if I try to configure the Apache Sling Request Parameter Handling to set the "Default Parameter Encoding", there is this error in my error.log file

In web console everything looks fine but the parameters are handled properly - there is the default ISO-8859-1 encoding used instead of the one I set. After that I tried to set the "Temporary File Location" to something different than the default empty value and everything works fine.

Could you please fix this? Or at least show the user some error message in web console instead of hiding it in log?
