Description
Issue Summary
When using Bitbucket Server 6.x with OpenJDK 11, there are warnings on Hazelcast both on the application and launcher logs.
Steps to Reproduce
- Install OpenJDK 11
- Install Bitbucket 6.8.0
- Ensure that Bitbucket is using this OpenJDK 11
- Start Bitbucket Server
- Check atlassian-bitbucket.log and launcher.log
Expected Results
Hazecast should be working with OpenJDK 11. Thus, the warning message should not be produced.
Actual Results
The below warning message is shown on atlassian-bitbucket.log:
