MetadataFactory datatype issue on boot up ----------------------------------------- Key: TEIID-2536 URL: https://issues.jboss.org/browse/TEIID-2536 Project: Teiid Issue Type: Bug Components: Server Affects Versions: 8.1 Reporter: Van Halbert Assignee: Steven Hawkins Labels: 8.4.Final Fix For: 8.4 Occurs on server startup. Deployed a vdb and was able to connect, etc. Bounced the server and now get a bunch of these errors: 21:03:39,432 ERROR [org.jboss.threads.executor] (teiid-async-threads - 1) Task execution failed for task org.teiid.jboss.VDBService$6@54241d18: java.lang.NullPointerException at org.teiid.metadata.MetadataFactory.addDatatype(MetadataFactory.java:589) [teiid-api-8.4.0.CR2-SNAPSHOT.jar:8.4.0.CR2-SNAPSHOT] at org.teiid.metadata.MetadataFactory.correctDataTypes(MetadataFactory.java:583) [teiid-api-8.4.0.CR2-SNAPSHOT.jar:8.4.0.CR2-SNAPSHOT] at org.teiid.metadata.MetadataFactory.correctDatatypes(MetadataFactory.java:559) [teiid-api-8.4.0.CR2-SNAPSHOT.jar:8.4.0.CR2-SNAPSHOT] at org.teiid.jboss.VDBService$6.run(VDBService.java:367) [teiid-jboss-integration-8.4.0.CR2-SNAPSHOT.jar:8.4.0.CR2-SNAPSHOT] at org.jboss.threads.SimpleDirectExecutor.execute(SimpleDirectExecutor.java:33) at org.jboss.threads.QueueExecutor.runTask(QueueExecutor.java:806) at org.jboss.threads.QueueExecutor.access$100(QueueExecutor.java:45) at org.jboss.threads.QueueExecutor$Worker.run(QueueExecutor.java:847) at java.lang.Thread.run(Thread.java:722) [rt.jar:1.7.0_09-icedtea] at org.jboss.threads.JBossThread.run(JBossThread.java:122) ------------ Looking at MetadataFactory I noticed the following: Datatype dt = this.builtinDataTypes.get(c.getDatatype().getName()); if (dt != null) { c.setDatatype(dt); } else { //must be an enterprise type //if it's used in a single schema, we're ok, but when used in multiple there's an issue --> addDatatype(dt); } } --------- that addDatatype(dt) was passing dt when null, and therefore, in addDatatype, the NPE was caused when datatype.getName() is called. But I think what was intended was to pass in c.getDatatype() when it wasn't found in the builtinDataTypes.
