UnsupportedOperationException when calling addPackage on rulebase
-----------------------------------------------------------------

                 Key: JBRULES-1512
                 URL: http://jira.jboss.com/jira/browse/JBRULES-1512
             Project: JBoss Drools
          Issue Type: Bug
      Security Level: Public (Everyone can see)
    Affects Versions: 4.0.4
            Reporter: Mattias Nilsson
         Assigned To: Mark Proctor
            Priority: Minor
         Attachments: global-test.zip

While migrating from Drools 3.0.6 to 4.0.4 a customer of ours found a bug. If you load two DRL files with same package declaration using two package builders into one rulebase, and only the second DRL file contains globals, the rulebase will throw an exception when loading the second package. This used to work in 3.0.6 but fails in 4.0.4. The following exception is thrown:

java.lang.UnsupportedOperationException
at java.util.AbstractMap.put(AbstractMap.java:228)
at java.util.AbstractMap.putAll(AbstractMap.java:317)
at org.drools.common.AbstractRuleBase.mergePackage(AbstractRuleBase.java:495)
at org.drools.common.AbstractRuleBase.addPackage(AbstractRuleBase.java:399)

I will upload an example that reproduces this problem.
