@MBaesken Could not automatically backport ecfb6bce to openjdk/jdk17u-dev due to conflicts in the following files:

  • src/hotspot/share/code/codeCache.cpp
  • src/hotspot/share/jfr/metadata/metadata.xml
  • test/jdk/jdk/jfr/event/compiler/TestJitRestart.java
  • test/lib/jdk/test/lib/jfr/EventNames.java

Please fetch the appropriate branch/commit and manually resolve these conflicts by using the following commands in your personal fork of openjdk/jdk17u-dev. Note: these commands are just some suggestions and you can use other equivalent commands you know.

# Fetch the up-to-date version of the target branch
$ git fetch --no-tags https://git.openjdk.org/jdk17u-dev master:master

# Check out the target branch and create your own branch to backport
$ git checkout master
$ git checkout -b MBaesken-backport-ecfb6bce

# Fetch the commit you want to backport
$ git fetch --no-tags https://git.openjdk.org/jdk ecfb6bce5a9878d7bedce47da60f96fa9146acf7

# Backport the commit
$ git cherry-pick --no-commit ecfb6bce5a9878d7bedce47da60f96fa9146acf7
# Resolve conflicts now

# Commit the files you have modified
$ git add files/with/resolved/conflicts
$ git commit -m 'Backport ecfb6bce5a9878d7bedce47da60f96fa9146acf7'

Once you have resolved the conflicts as explained above continue with creating a pull request towards the openjdk/jdk17u-dev with the title Backport ecfb6bce5a9878d7bedce47da60f96fa9146acf7.
