Daniel Straub commented on JBAS-7614:
-------------------------------------
I added the LegacyPrefixDeploymentContextComparator to a jboss-5.1.0 instance and modifed
bootstrap/deployers.xml.
It's works for simple jar, but throws an NPE by an deployment of ear with many jars.

I found the reason in
org.jboss.deployers.structure.spi.helpers.AbstractStructureBuilder.applyComparator.
A instance of the LegacyDeploymentContextComparator is created whose
"create"-method isn't called.
if (o == null)
o = clazz.newInstance();
Comparator comparator = Comparator.class.cast(o);
context.setComparator(comparator);
As workaround, I added also the LegacyDeploymentContextComparator in
bootstrap/deployers.xml like this :
<!-- use legacy ordering -->
<bean name="topContextComparator">
<constructor
factoryClass="org.jboss.system.deployers.LegacyPrefixDeploymentContextComparator"
factoryMethod="getInstance"/>
</bean>
<bean name="otherContextComparator">
<constructor
factoryClass="org.jboss.system.deployers.LegacyDeploymentContextComparator"
factoryMethod="getInstance"/>
</bean>
so we have the singelton instance whose "create"-Method was called during the
lifecycle.
