Run the 'ant install.demo', all OK. Run 'ant start.demo', all OK except the eclipse start failed somewhere. I start eclipse by hand as supplied by jbpm5 installer, select jbpm5-installer workspace and import the sample project. Project does not configure until I select the jbpm5 runtime in preferences, then restart eclipse, try to run the ProcessTest as Java App, fails with:

java.lang.NoSuchMethodError: org.drools.rule.TypeDeclaration.setTypesafe(Z)V

This is provided in the project by jbpm and listed as the drools-core-5.2.0.CR1.jar so not missing the method in project?
