The VM option -XX:AllowRedefinitionToAddDeleteMethods was added in JDK 13 as a temporary backward compatibility flag under JDK-8192936 and was immediately marked as Deprecate. The fix is to obsolete this option in JDK 26 and expire in JDK 27.
There are two concerns which may require some negotiation with the Runtime (@coleenp @dcubed-ojdk @dholmes-ora) and SQE (@lmesnik) teams: - Class redefinition/retransformation can impact lambda expressions which are supported with private methods - Many tests depend on this VM option and are being removed. I'm not sure if it is okay to completely remove those e may want another way to handle this (e.g. problem-listing the impacted tests for now). Testing: - mach5 tiers 1-6 are good - may need to run mach5 tiers > 6 ------------- Commit messages: - 8358890: VM option -XX:AllowRedefinitionToAddDeleteMethods should be obsoleted then expired Changes: https://git.openjdk.org/jdk/pull/26232/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=26232&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8358890 Stats: 1851 lines in 36 files changed: 0 ins; 1825 del; 26 mod Patch: https://git.openjdk.org/jdk/pull/26232.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/26232/head:pull/26232 PR: https://git.openjdk.org/jdk/pull/26232
