[jboss-jira] [JBoss JIRA] Closed: (JBRULES-1512) UnsupportedOperationException when calling addPackage on rulebase

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 Fix For: 4.0.7, 5.0.0-M1 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.
