NIFI-7683: Fixed bug that resulted in a byte[] being allocated and held onto by
a member variable that was unprotected. This caused the byte array to be
modified by two different threads concurrently, which can potentially cause
corruption of FlowFile's data

This closes #4439
> ReplaceText with multiple concurrency tasks can result in data corruption

> Project: Apache NiFi

>
> 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.
