Hi there, i also currently am experiencing this exception and found some other bugs that are talking about this. Most fitting probably would be Bug 371586. A (blunt?) workaround mentioned there (in Bug 371586 Comment 2 - https://bugs.eclipse.org/bugs/show_bug.cgi?id=371586#c2) would be to add -Djava.util.Arrays.useLegacyMergeSort=true to your eclipse.ini. Maybe someone who reads this can add the abovementioned Bug to the seealso field(s)? HTH Daniel P.S.: https://dertompson.com/2012/11/23/sort-algorithm-changes-in-java-7/ is also talking about the underlying phenomenon.

The workaround works for me in Eclipse 2022-12
