App classloader leaked by IIOP WorkCacheManager cache

Details

    Description

      After redeploys, application ear module classloaders are left in org.wildfly.iiop.openjdk.rmi.WorkCacheManager's classesByLoader map:

      com.sun.corba.se.impl.transport.SelectorImpl @ 0xc12234b8  SelectorThread Thread
'- contextClassLoader org.jboss.modules.ModuleClassLoader @ 0xc075bea0
   '- classes java.util.Vector @ 0xc075c4a8
      '- elementData java.lang.Object[160] @ 0xc1afb200  
         '- [58] class org.wildfly.iiop.openjdk.rmi.ValueAnalysis @ 0xc180e4b0  |
            '- cache org.wildfly.iiop.openjdk.rmi.WorkCacheManager @ 0xc180e520
               |- classesByLoader java.util.HashMap @ 0xc180e730
               |  '- table java.util.HashMap$Node[16] @ 0xc1ba2ff8 
               |     |- [14] java.util.HashMap$Node @ 0xc37b01e0 
               |     |  '- key org.jboss.modules.ModuleClassLoader @ 0xc3677958

      This was previously a weak map, but we switched to strong caching with explicit clean up on undeploy. It looks like that clean up is missed in some case.

          Bug - A problem that impairs or prevents the functions of the product. JBEAP-16465 [GSS](7.2.z) WFLY-11784 (WF part) - app classloader leaked by IIOP WorkCacheManager cache

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
