Concurrency issue in StaxUtils.createXMLStreamReader
----------------------------------------------------
Key: XFIRE-1001
URL: http://jira.codehaus.org/browse/XFIRE-1001
Project: XFire
Issue Type: Bug
Components: Core
Affects Versions: 1.2.6
Environment: Windows XP, Java 5 update 9
Reporter: Walter Seymore
Assignee: Dan Diephouse
Attachments: HelloWorldClient.java, HelloWorldService.java
I've created a simple HelloWorld service that echoes a name back to the client.
This works fine until i create 2 or more threads that calls the service at the
same time. Every now and then, I get an XML parsing error. The content of the
request is always correct however and making this small change to StaxUtils
fixes the issue.
759 synchronized(factory) {
760 return factory.createXMLStreamReader(in, encoding);
761 }
So this would indicate that it is not safe to use the same XMLInputFactory
instance in a multi-threaded way. Obviously synchronisation is not an optimal
solution, but hopefully you guys can think of something better :).
