JBPM 6.4 - Failed to deploy kjar (doesn't recognize Java version)

[s.jain]

I've been using JBPM 6.3 for more than 6 months and now planning to move to JBPM 6.4. I couldn't build my project on JBPM 6.4 that was working fine on JBPM 6.3

So, I downloaded JBPM 6.4 again and tried to build a project on out of the box jbpm-installer's sample projects:

1. Unzip the zip

2. ant install.demo.noeclipse

3. ant start.demo.noeclipse. jbpm-cosole and kie-server got deployed successfully.

4. Logged in as admin

5. Opened Project Authoring ->demo ->uf-playground->mortgages.

6. CIicked on "Open Project Editor", then Build ->Build and Deploy.

I got following errors.

Syntax error, annotations are only available if source level is 1.5 or greater

I am on Java 1.8.0_91. I am not sure how to configure JBPM workbench to specify Java version.
