The error was thrown while the search was in progress. NetBeans tried to recognize MIME-Type of an XML file with a very long attribute in the root tag (or an attribute containing an entity which resolved in a long string, something like [1]).

I'm not sure this artificial case should be handled by NetBeans.
Closing as WONTFIX for now, as it seems that the file was accessed accidentally, and the fix could be dangerous (affect performance or break some MIME resolvers).

Please reopen this issue if you need to work with XML files with very long attribute values.

Occurred in NetBeans 7.1.1, which is quite old.

Thank you for reporting.
