There was a problem hiding this comment.
The Javadoc only mentions endless loops ("if the search is repeating and there is an endless loop"). It would be clearer if it also included a mention of the TTL to avoid confusion.

There was a problem hiding this comment.
I would suggest adding an example of IllegalStateException with a shorter input, like:
assertThrows(
IllegalStateException.class,
() -> StringUtils.replaceEachRepeatedly("aaaaaab", new String[] {"ab"}, new String[] {"b"}),
"Should be a circular reference");
It might surprise newcomers that even far fewer than 32 repetitions can trigger an IllegalStateException.

Thanks for the fix! Seems perfect for us. |

The method
replaceEachRepeatedlycallsreplaceEachrepeatedly until no more replacements are possible ortimeToLive < 0. ThetimeToLivestarts with the value ofsearchList.length. The current implementation can't distinguish between infinite loops and deeply nested string patterns. In both cases, it continues replacements until it hits the time-to-live limit and throwsIllegalStateExceptionif replacements are still possible.The problem with LANG-1528 fix is that in some cases, it allows partially replaced strings after TTL is exceeded. This fix reverts
replaceEachlogic back to version 3.10 (see PR #505), but allows deeper dives due to an increased initial TTL value. The initial TTL value is now set to the greater ofsearchList.lengthor up to 5 levels deep. This default value was chosen based on rational considerations.
