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
- Create a parameterized requestor level data page. In the load activity, refer another requestor level data page.
- 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.
