[rules-users] Exception when trying to find a field when debugging

Hello,

I have an object with a timestamp field which I declared this way in my rule
file: 

/declare VpAction
    @role( event )
    @timestamp ( myGregorianCalendar.getTimeInMillis())
end /

where myGregorianCalendar is from type java.util.GregorianCalendar.

Using the rule file in my application works fine (and the timestamp of the
events is recognized correctly, comparisons of events like 'before' and
'after' work too), but when I try setting a breakpoint within this rule
file, I get an exception (see below).

Nevertheless the breakpoint appears as 'set'. But when I debug my
application as a drools application, all breakpoints of my rule file are
skipped, so debugging is impossible. My other rule files don't have event
declarations and the exception doesn't appear there and the rules there are
debuggable.

Any ideas? Thanks in advance!

Here is the exception:
