Hi Is there a way to set the target level (ie jdk 1.5) when building a rules package (especially with the drools-ant task)? Browsing the source code, I found the drools.dialect.mvel.langLevel (and same for java), but settings those in ant doesn't seem to do the trick: building the rules under jdk1.6 produces 1.6 target classes which can't be reloaded again with jdk1.5.
