  "message": "RepoUpdater: Convert ConcurrentRefUpdateException into LockFailureException\n\nCalling the RepoCommand may fail with a ConcurrentRefUpdateException\nthat represents a LOCK_FAILURE. Convert this exception into a\nLockFailureException so that our auto-retrying logic for LOCK_FAILURES\ncan recognize the LOCK_FAILURE and retry the operation, instead of\nfailing immediately.\n\nExample stacktrace:\nupdate for foo/manifest:*:default.xml (Repo) \u003d\u003e foo/superproject:* (ref refs/heads/main) failed: org.eclipse.jgit.api.errors.ConcurrentRefUpdateException: Cannot lock refs/heads/main. Ensure that no other process has an open file handle on the lock file refs/heads/main.lock, then you may delete the lock file and retry.. RefUpdate return code was: LOCK_FAILURE\n\tat org.eclipse.jgit.gitrepo.BareSuperprojectWriter.commitTreeOnCurrentTip(BareSuperprojectWriter.java:311)\n\tat org.eclipse.jgit.gitrepo.BareSuperprojectWriter.write(BareSuperprojectWriter.java:141)\n\tat org.eclipse.jgit.gitrepo.RepoCommand.call(RepoCommand.java:573)\n\tat com.googlesource.gerrit.plugins.supermanifest.RepoUpdater.update(RepoUpdater.java:74)\n\tat com.googlesource.gerrit.plugins.supermanifest.SuperManifestRefUpdatedListener.updateForConfig(SuperManifestRefUpdatedListener.java:424)\n\tat com.googlesource.gerrit.plugins.supermanifest.SuperManifestRefUpdatedListener.onGitReferenceUpdated(SuperManifestRefUpdatedListener.java:314)\n\nFollow the example of change I2ff60b01a in gerrit core.\n\nChange-Id: I46be2ee251bfef9dee4ea65c3f689415095501dd\nSigned-off-by: Edwin Kempin \u003cekempin@google.com\u003e\n",
