ConcurrentModificationException on asynchronous data page load

SA-44550

Summary



Concurrent Modification exception occurs when the system loads a data page asynchronously.


Error Messages



Not Applicable


Steps to Reproduce

  1. Create a parameterized requestor level data page. In the load activity, refer another requestor level data page.
  2. Trigger a data page to load asynchronously.


Root Cause



A node level data page expands by invoking the expand(true, true). However, this does not expand the PropertyStreams. As a result, the exception occurs while expanding the PropertyStreams when two PRThreads copy from the same node level page.

Resolution



Apply HFix-35509.
