Hello All,

I am investigating Drools Guvnor for its rule authoring capabilities.

The site says the Gunor License is ASL but it packages hibernate jars. Hibernate license is LGPL.

I removed the hibernate jars from Guvnor & still it is able to perform db operations.

Note: Guvnor is using Oracle database as a repository (not using the default file system repo). Repository file attached.

Question:
1. Does Guvnor uses hibernate jars? If yes then in what scenarios. (I am able to do create rules in repo (database) without hibernate jars)
2. Is hibernate a leftover from old versions of drools ? Why is it packaged with drools 5.1 guvnor release ?

Tasks performed to proove that Guvnor does not have any dependency on hibernate.

1. Stopped the JBOSS server
2. Removed hibernate jars from guvnor lib folder.

3. Started Guvnor
3. Created rules in guvnor. I verified that the new rules were getting stored in the database.

Hence no dependency of guvnor on Hibernate.
