rule x
when
   # ... bind 2 int and 2 long, making sure that
   # $int1 == 1 and $int3 == 65536...

   eval( $int1 == $long2 == $int3 == $long4 )
then
   // print all 4 values
end

Using dialect "java" this results in a syntax error, which is to be expected.

Dialect "mvel" evaluates this to true for a surprising range of integer values.
Here is a selection:

1 1 65536 1234567890
1 1 65536 424242
1 1 65536 65536
1 1 65536 4294967296
1 1 65536 65568
1 1 65536 65552

Is there any logic behind this?
