Subject [jira] Created: (HARMONY-6236) ArrayList breaks when given concurrent collections as input
Date Mon, 15 Jun 2009 22:28:07 GMT
ArrayList breaks when given concurrent collections as input
-----------------------------------------------------------

                 Key: HARMONY-6236
                 URL: https://issues.apache.org/jira/browse/HARMONY-6236
             Project: Harmony
          Issue Type: Bug
          Components: Classlib
    Affects Versions: 5.0M10
         Environment: SVN Revision: 784898
            Reporter: Jesse Wilson


new ArrayList() and ArrayList.addAll(Collection) assume the passed-in collection will not
change between calls. 

In the attached test case, a special collection simulates a background thread calling "remove"
after the ArrayList has called size(), but before it has called "toArray()". This causes the
collection to return a null-padded array, which leads to a corrupt ArrayList. The attached
patch fixes the problem.
