[jboss-jira] [JBoss JIRA] (DROOLS-61) Classes with package protected visibility cannot be used in rules defined in the same package

[Mario Fusco (JIRA)]

     [ https://issues.jboss.org/browse/DROOLS-61?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Mario Fusco resolved DROOLS-61.
-------------------------------

    Fix Version/s: 5.6
                   6.0.0.Alpha1
       Resolution: Done


It is not possible to make this use case to work because both the drools compiler and mvel has no notion of the package to which a given rule, pattern, statement or expression belongs to.

I fixed this issue raising a proper compilation failure every time you use a non-public class inside a DRL.
