I am using OpenJDK 1.7 to run Planner (which requires at least 1.6) and therefore drools.
All planner stuff is compiled -source 1.6 and -target 1.6.

I haven't tried a drools using project with -source 1.7 and -target 1.7 yet.
If that fails (and you can verify that -source 1.6 and -target 1.6 solves it) then please raise a jira and link that jira here.

I'm implementing my model with drools 5.5.0.Final and JDK 1.7 without any issue, my only problem is the lack of knowledge on drools hehe.

Does anyone know of a compatibility matrix that shows what JDK versions are
compatible with Drools 5.5? The documentation mentions at least Java 1.5 is
needed, and says some examples may need 1.6.

I have encountered a problem when classes are compiled with Java 1.7, in
that if they are referenced by a DRL file, the rules compiler gives the
error "[Class] cannot be resolved to a type" for the classes that were
compiled (actually the whole jar) with Java 1.7.

Here is my post when I was trying to resolve that compile issue:
Previous post on [Class] cannot be resolved to a type error

The rule compiler error went away when I recompiled the classes and deployed
the jar using Java 1.6. Anyone else have an issue with 1.7, or know if
Drools 5.5 is supposed to be compatible?

Thanks,
rb
