[jboss-jira] [JBoss JIRA] Created: (JBRULES-739) Exception reading PackageBuilder errors

Exception reading PackageBuilder errors --------------------------------------- Key: JBRULES-739 URL: http://jira.jboss.com/jira/browse/JBRULES-739 Project: JBoss Rules Issue Type: Bug Security Level: Public (Everyone can see) Components: Drl Parser/Builder Affects Versions: 3.1-m2 Reporter: Dirk Bergstrom Assigned To: Mark Proctor Attachments: Bug.java Using trunk (revision 10170), I get an exception when trying to read errors after calling PackageBuilder.addPackageFromDrl(String, Reader) with any DSL file. The getErrors() method spits out this exception: java.lang.ArrayStoreException at java.lang.System.arraycopy(Native Method) at java.util.ArrayList.toArray(ArrayList.java:304) at org.drools.compiler.PackageBuilder.getErrors(PackageBuilder.java:380) (The docs for toArray say that exception is thrown if one of the members of the List is the wrong class for the supplied array.) If I instead call printErrors, I get something more useful: java.lang.ClassCastException: org.drools.lang.ExpanderException at org.drools.compiler.PackageBuilder.printErrors(PackageBuilder.java:390) If I call PackageBuilder.addPackageFromDrl(String), I get no errors. So there are two issues: *) The DSL parser is busted *) PackageBuilder is putting incompatible Exceptions in the errors Collection. -- 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
