In git master, running this test, a request for such a huge string gives me an
{{{}java.lang.OutOfMemoryError: Java heap space{}}}, no surprise there.

> Key: LANG-1824
> URL: https://issues.apache.org/jira/browse/LANG-1824
> Project: Commons Lang
> Issue Type: Bug
> Components: lang.*
> Affects Versions: 3.20.0
> Reporter: Veijo Vainionpää
> Priority: Major
>
> NegativeArraySizeException thrown from Strings.replace with larger
> replacement when {{replacement.length() - searchString.length()}} is bigger
> than 134217727 bytes (~132 MB).
> {{public String replace(final String text, String searchString, final String
> replacement, int max) {}}
> {{...}}
> {{final int replLength = searchString.length();}}
> {{int increase = Math.max(replacement.length() - replLength, 0);}}
> {{increase *= max < 0 ? 16 : Math.min(max, 64);}}
> {{final StringBuilder buf = new StringBuilder(text.length() + increase);}}
> {{...}}
> {{}}}
> The main reason is that the integer overflows after multiplication.
