[rules-dev] Drools OSGi issue

[shelly handa]

Hi,

I am trying to integrate the drools with OSGi.
I have included all the drools dependencies in pom.xml.
In error stack trace it says error about ruleMemo field present
antler osgified jar.

"ruleMemo" field lies in org.antlr.runtime.RecognizerSharedState class.
can any body help me.

Regards,
Shelly

I am getting the following error:

java.lang.NoSuchFieldError: ruleMemo
