The test fails with:
FAILED: java/text/Format/NumberFormat/IntlTestDecimalFormatSymbols.java

Reason being:

IntlTestDecimalFormatSymbols {
  TestSymbols {
    ERROR: English minus sign not equal to Croatian minus sign. Got: \u2212 expected: -
    Uncaught exception thrown in test method TestSymbols

The test passes with JDK 11.0.18. So this seems a regression in JDK 17+
