[jboss-osgi-issues] [JBoss JIRA] Commented: (JBOSGI-107) MC beans cannot be redeployed after refresh

[Thomas Diesler (JIRA)]

    [ https://jira.jboss.org/jira/browse/JBOSGI-107?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12472923#action_12472923 ] 

Thomas Diesler commented on JBOSGI-107:
---------------------------------------

The underlying issue is that BeansDeployer uses an JBossXBDeployerHelper

BeansDeployer -> SchemaResolverDeployer -> JBossXBDeployer

The JBossXBDeployerHelper uses 

   private static DefaultSchemaResolver resolver = (DefaultSchemaResolver)SingletonSchemaResolverFactory.getInstance().getSchemaBindingResolver();

which internally caches the classes.

>From what I can see SingletonSchemaResolverFactory is evil and cannot be used in an OSGi environment.
