Bjørn Erik Lømo commented on JBRULES-2102:
--------------------------------------------
In the aforementioned example, if both members are Integer objects, one of them being a
nullpointer: If the right hand side of an Integer > Integer comparison is a
nullpointer, drools throws a NPE. If the left hand side is null, it works fine.
There's a check missing for null values on object2 in this function:
public boolean evaluate(InternalWorkingMemory workingMemory,
final InternalReadAccessor extractor1,
final Object object1,
final InternalReadAccessor extractor2, final Object
object2) {
if( extractor1.isNullValue( workingMemory, object1 ) ) {
return false;
}
return extractor1.getIntValue( workingMemory, object1 ) >
extractor2.getIntValue( workingMemory, object2 );
}
Etirelli can probably fill in the rest.
