[infinispan-issues] [JBoss JIRA] (ISPN-4354) Unable to use custom keys/values with clustered caches in OSGi

[Ion Savin (JIRA)]

    [ https://issues.jboss.org/browse/ISPN-4354?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12973825#comment-12973825 ] 

Ion Savin commented on ISPN-4354:
---------------------------------

The classloader used to load these classes by default is the classloader of GlobalConfigurationBuilder which should be the classloader of the org.infinispan.core bundle.

At the moment just the org.infinispan.commons bundle is using Dynamic-Import: *  in the header. It will need to be added to the core bundle also.

The stack reports org.jgroups as the bundle trying to load the class because the tests repackage the core jar and make it a fragment of the jgroups bundle.
