Here, I've found this for you, a comment from the Drools source file
org.drools.rule.builder.dialect.java.JavaDialectConfiguration

* There are options to use various flavours of runtime compilers.
* Apache JCI is used as the interface to all the runtime compilers.
*
* You can also use the system property "drools.compiler" to set the
desired compiler.
* The valid values are "ECLIPSE" and "JANINO" only.
*
* drools.dialect.java.compiler = <ECLIPSE|JANINO>
* drools.dialect.java.lngLevel = <1.5|1.6>
*
* The default compiler is Eclipse and the default lngLevel is 1.5.
* The lngLevel will attempt to autodiscover your system using the
* system property "java.version"
*
* The JavaDialectConfiguration will attempt to validate that the
specified compiler
* is in the classpath, using ClassLoader.loasClass(String). If you intented to
* just Janino sa the compiler you must either overload the compiler
property before
* instantiating this class or the PackageBuilder, or make sure
Eclipse is in the
* classpath, as Eclipse is the default.

Try it without the JANINO setting - it *should* flag the setter with
the incompatible types.

If you haven't used MVEL so far, I don't see any reason to start now.
