* Bug 66425: Avoid exceptions found via poi-fuzzDominik Stadler2025-01-201-6/+15
| | | | | | | | | | | | | | Prevent too deep nesting by throwing an exception instead of just not parsing more nesting-levels as this still caused OOMs. Allow to adjust the limit via static setter as elsewhere to give users a chance to parse very complicated files if really necessary. https://issues.oss-fuzz.com/issues/42528505 git-svn-id: https://svn.apache.org/repos/asf/poi/trunk@1923277 13f79535-47bb-0310-9956-ffa450edef68

| | | | | | | | | | | | | JDK 23 removes the COMPAT/JRE locale provider which causes some changes to string formatting Default German data format changed and thus we need to introduce a custom format.
