[rules-users] Dynamic Rules and Eval

[rrdh]

5.2.0 does work. Thank you again! I've been trying all day to somehow get
around this.

I just had to add this to META-INF/drools.default.packagebuilder.conf in
drools-compiler-5.2.0.Final.jar to be able to use it with Java 7:

drools.dialect.java.compiler = ECLIPSE
drools.dialect.java.lngLevel = 1.6
drools.dialect.java.compiler.lnglevel = 1.6
