Another attempt to fix o.o.transport.netty4.OpenSearchLoggingHandlerIT fails w/ stack overflow

[reta]

Signed-off-by: Andriy Redko andriy.redko@aiven.io

Description

This time no guesses, I was able to reproduce the issue. The Netty dumps raw messages (in hex) into logs and for some specific rare patterns (I have an example), the appender filter blows with StrackOverflowError. The change to appender filter to watch only for single line log statements (expressed in expectations) fixed the issue.

The backport to 1.2 failed:

The process '/usr/bin/git' failed with exit code 1

To backport manually, run these commands in your terminal:

# Fetch latest updates from GitHub
git fetch
# Create a new working tree
git worktree add .worktrees/backport-1.2 1.2
# Navigate to the new working tree
cd .worktrees/backport-1.2
# Create a new branch
git switch --create backport/backport-2051-to-1.2
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x --mainline 1 1e5d98329eaa76d1aea19306242e6fa74b840b75
# Push it to GitHub
git push --set-upstream origin backport/backport-2051-to-1.2
# Go back to the original working tree
cd ../..
# Delete the working tree
git worktree remove .worktrees/backport-1.2

Then, create a pull request where the base branch is 1.2 and the compare/head branch is backport/backport-2051-to-1.2.
