Walter, that thread you linked to looks like it's a similar problem but actually it's unrelated. That person had an issue with the Java YPCLSP.dll library (related to Yahoo Parental Controls, as that site says).
Phoenix32890, there are 2 posibilities:
Either the Java library that crashed has been corrupted or is out of date for a program which requires it, or a program which uses that Java plugin is improperly accessing it.
It
might be an exploit type trojan that your virus scanner doesn't consider a virus since it is only a prelude to virus. Possibly it's an incorrect function call to a dll by a mother trojan.
If I were you though, I wouldn't really worry about it too much. But let us know if you ever get the same error log again.
