This is 8u-specific issue. It's a prerequisite for backport of 2024b (JDK-8339637) as backporting 2024b to 8u as is leads to the following failure

java.lang.IllegalArgumentException: Unknown region: HST
at build.tools.tzdb.TzdbZoneRulesCompiler.findRegionIndex(TzdbZoneRulesCompiler.java:290)
at build.tools.tzdb.TzdbZoneRulesCompiler.outputFile(TzdbZoneRulesCompiler.java:259)
at build.tools.tzdb.TzdbZoneRulesCompiler.compile(TzdbZoneRulesCompiler.java:193)
at build.tools.tzdb.TzdbZoneRulesCompiler.main(TzdbZoneRulesCompiler.java:91)

JDK-8042369 updated the compiler to ignore HST/EST/MST links in 9+ (https://hg.openjdk.org/jdk9/jdk9/jdk/rev/6c26f18d9bc0#l8.139) so the failure didn't appear with backports of 2024b to 11+
