-----------------------------------
how does this happen? Did I introduce this?
> ReplaceText can product StackOverflowError which causes admin yield
> -------------------------------------------------------------------

> Key: NIFI-5274
> URL: https://issues.apache.org/jira/browse/NIFI-5274
> Project: Apache NiFi
> Issue Type: Bug
> Components: Extensions
> Affects Versions: 1.6.0
> Reporter: Michael Moser
> Assignee: Michael Moser
> Priority: Major
>
> Regex Replace mode can easily produce StackOverflowError. Certain regular
> expressions are implemented using recursion, which when used on large input
> text can cause StackOverflowError. This causes the ReplaceText processor to
> rollback and admin yield, which causes the input flowfile to get stuck in the
> input queue.
> We should be able to catch this condition and route the flowfile to failure.
