Mark Payne updated NIFI-7683:
-----------------------------
Description:
ReplaceText, when scheduled to run with multiple Concurrent Tasks, and using a
Replacement Strategy of "Regular Expression" or "Literal Replace" can result in
content being corrupted by sharing a single buffer (byte[]) between threads.
The issue is far more likely to occur with multiple Concurrent Tasks, but it
may be possible to trigger when using a single Concurrent Task.
