The `jdk.internal.ValueBased` annotation was incorrectly applied to subclasses of java.util.AbstractMap. [ValueBased](https://docs.oracle.com/en/java/javase/17/docs/api/java.base/java/lang/doc-files/ValueBased.html) requires that supertypes have no instance fields; AbstractMap has instance fields keySet and values.
Remove the internal @ValueBased annotation for subclasses of AbstractMap including: AbstractImmutableMap, Map1, and MapN. ------------- Commit messages: - 8272042: java.util.ImmutableCollections$Map1 and MapN should not be @ValueBased Changes: https://git.openjdk.java.net/jdk/pull/6480/files Webrev: https://webrevs.openjdk.java.net/?repo=jdk&pr=6480&range=00 Issue: https://bugs.openjdk.java.net/browse/JDK-8272042 Stats: 3 lines in 1 file changed: 0 ins; 3 del; 0 mod Patch: https://git.openjdk.java.net/jdk/pull/6480.diff Fetch: git fetch https://git.openjdk.java.net/jdk pull/6480/head:pull/6480 PR: https://git.openjdk.java.net/jdk/pull/6480
