Please review this trivial cleanup PR which removes the nested static private class `System.CallersHolder`.
This class was used pre JEP486 to track callers of `System::setSecurityManager` such that warnings were printed only once per caller. This seems like a leftover from JEP-486 which would be nice to clean up. ------------- Commit messages: - Remove nested static private class System.CallersHolder Changes: https://git.openjdk.org/jdk/pull/22167/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=22167&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8344336 Stats: 7 lines in 1 file changed: 0 ins; 7 del; 0 mod Patch: https://git.openjdk.org/jdk/pull/22167.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/22167/head:pull/22167 PR: https://git.openjdk.org/jdk/pull/22167
