Hi Gang! Congrats on developing a very robust feature set for a rule engine package! I've downloaded Drools source and I'm able to build all artifacts on Mac OS X 10.5.6 using Java 1.6.0_07 on Intel Core 2 Duo hardware. However, some of the unit tests aren't passing -- am I correct in assuming that Drools has not been upgraded to use Java 1.6? I tried rebuilding under Java 1.5.0_16 and I do *not* get this error.
