[jboss-jira] [JBoss JIRA] Created: (JBRULES-1211) Rules with accumulators cannot be serialized

Rules with accumulators cannot be serialized -------------------------------------------- Key: JBRULES-1211 URL: http://jira.jboss.com/jira/browse/JBRULES-1211 Project: JBoss Rules Issue Type: Bug Security Level: Public (Everyone can see) Components: Drl Parser/Builder Affects Versions: 4.0.1 Reporter: Laszlo Muller Assigned To: Mark Proctor If a rulesbase includes a max accumulator then it cannot be serialized. The org.drools.base.accumulators.AccumulateFunction interface does not extend Serializable and none of its default implementations implement it either. When you try to serialize such a Package you get the following exception: java.io.NotSerializableException: org.drools.base.accumulators.MaxAccumulateFunction at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1054) at java.io.ObjectOutputStream.defaultWriteFields(ObjectOutputStream.java:1332) at java.io.ObjectOutputStream.writeSerialData(ObjectOutputStream.java:1304) at java.io.ObjectOutputStream.writeOrdinaryObject(ObjectOutputStream.java:1247) at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1052) at java.io.ObjectOutputStream.writeObject(ObjectOutputStream.java:278) at java.util.HashMap.writeObject(HashMap.java:980) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:324) at java.io.ObjectStreamClass.invokeWriteObject(ObjectStreamClass.java:809) at java.io.ObjectOutputStream.writeSerialData(ObjectOutputStream.java:1296) at java.io.ObjectOutputStream.writeOrdinaryObject(ObjectOutputStream.java:1247) at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1052) at java.io.ObjectOutputStream.writeObject(ObjectOutputStream.java:278) at org.drools.rule.PackageCompilationData.writeExternal(PackageCompilationData.java:116) at java.io.ObjectOutputStream.writeExternalData(ObjectOutputStream.java:1267) ... Paragraph 7.1.4.4. of the documentation clearly states that packages should be serializable. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
