[jbosstools-issues] [JBoss JIRA] Commented: (JBIDE-6450) Classloader incompatibilities between javax.xml.soap (1.2) and javax.xml.soap (1.3) when running WS Tester

Max Andersen commented on JBIDE-6450:
-------------------------------------

After having a chat with Chris A. at Eclipse Summit we found the diff between 1.2 and 1.3 is the following:

1.2 manifest.mf:
Export-Package: javax.xml.soap;version="1.2.0"

1.3 manifest.mf:
Export-Package: javax.xml.soap;version="1.3.0"; uses:="javax.activatio
 n,  javax.xml.namespace,  javax.xml.transform,  org.w3c.dom"

Chris's hunch said that the "uses" clause might cause org.w3c.dom to be "linked" to 1.3 even though our plugin is using 1.2 while also using org.w3c.dom.

Suggestion is to try remove the uses clause completely in 1.3 manifest.mf and see if that solves the problem.

If it does - we got a bugreport ;)

Brian, want to try this out ASAP and we might take it further ?

>    Affects Versions: 3.2.0.M1
>            Reporter: Brian Fitzpatrick

>            Priority: Critical

> Finally got to the heart of the java.lang.VerifyError issue I've been running into with the WS Tester. 
> javax.xml.soap (1.2) is an old-school plug-in jar wrapper that takes saaj.jar and exposes it in Eclipse.
> javax.xml.soap (1.3) is a new-school OSGI-compatible wrapper that builds the individual saaj classes and wraps them to expose them in Eclipse. 
> As Nick said in a recent IRC chat - ".jar!/org/whatever/*.class is better than .jar!foo.jar". But in my case, it causes the lovely java.lang.VerifyError when I try to use a utility class that takes advantage of classes from javax.xml.soap. 
> After doing some digging, it turns out the javax.xml.soap (1.3) plug-in is coming from the Atlassian update site for the latest & greatest version of their JIRA/Mylyn plug-ins. Without Atlassian JIRA connectors installed, it runs just fine. 
> So this presents an issue... If we're meant to certify against Atlassian JIRA connectors, this is going to come up again. So how do we work around it?
