> jbossrules\drools-core\src\main\java\org\drools\base\evaluators\BigIntegerFactory.java and BigIntegerFactory.java
> won't compile in 1.5 source because BigDecimal isn't a 100% backwards compatible from java 1.5 to 1.4,
> due to them generifying it.
> The fix is easy: just add some casts, the JVM does this at runtime anyway.
> For example:
>             final BigDecimal comp = (BigDecimal) extractor.getValue( object1 );
>             return comp.compareTo( object2.getValue() ) < 0;
> This code turns red in java source=1.5 in IntelliJ IDEA  (and in Eclipse I would expect the same?)
> Turn it into:
>             ...
>             return comp.compareTo( (BigDecimal) object2.getValue() ) < 0;
> I didn't create a patch as it's fast to fix: just copy-paste (BigDecimal) in the 2 classes's use of the compareTo method.
