Multiple JIRAs will not run in same JVM

Currently if multiple versions of JIRA are running the the same JVM, all instances but the first will fail with worfklow exceptions like the below:

java.lang.ClassCastException
at
com.opensymphony.workflow.config.ConfigLoader.load(ConfigLoader.java:99)
at
com.opensymphony.workflow.AbstractWorkflow.loadConfig(AbstractWorkflow.java:829)
at
com.opensymphony.workflow.AbstractWorkflow.<init>(AbstractWorkflow.java:78)

This is caused be the upgrade to OSWorkflow 2.6, which has some ugliness with the way that it loads classes.

This occurs in ConfigLoader.java from OSWorkflow in the following line:

if (Thread.currentThread().getContextClassLoader() != null) {
try

{ factory = (AbstractWorkflowFactory) Class.forName(clazz, true, Thread.currentThread().getContextClassLoader()).newInstance(); //factory = (AbstractWorkflowFactory) Thread.currentThread().getContextClassLoader().loadClass(clazz).newInstance(); }

catch (ClassNotFoundException e) {
//fall back to this class' classloader.

The commented line fixes the problem.

I will attach a fix - it looks like this will need to go back into OSWorkflow (who should really be using ClassloaderUtils.loadClass() anyhow.
