[jira] [Created] (COLLECTIONS-838) Calling SetUtils.union on multiple instances of SetView causes JVM to hang

Tanmay Ambre created COLLECTIONS-838:
----------------------------------------

             Summary: Calling SetUtils.union on multiple instances of SetView causes JVM to hang
                 Key: COLLECTIONS-838
                 URL: https://issues.apache.org/jira/browse/COLLECTIONS-838
             Project: Commons Collections
          Issue Type: Bug
          Components: Collection
    Affects Versions: 4.4
            Reporter: Tanmay Ambre
         Attachments: Test1.java

hi,

 

Please have a look at the attached test class. If I call the SetUtils.union multiple times (~40) the JVM hangs. However, it will complete if I reduce the iterations (~30).
