Is this a known issue? I could not find anything. I will remote debug and provide more details if you want, but for that I also need to know the revision id for release 6.2 in order to be in sync with the source code in my debugger.

[Simon Brandhof]

Hi,

We don't understand in which context this bug can be raised. Debugging to get more details on the related file would be much appreciated so that we can reproduce the bug.

Bug is tracked in https://jira.sonarsource.com/browse/SONAR-8835.

Thanks

Bernd, I may have found the issue. Do you confirm that you use Oracle ? If yes then it comes from the fact that empty strings are considered as null on Oracle.

The bug is still planned to be fixed in 6.4.

Thanks

[Bernd Götz]

Hi Simon, yes, I am using Oracle. Great to hear you could identify the issue. By when can we expect to have 6.4 available?

[Simon Brandhof]

Finally this issue is fixed in 6.3 and will be available in next RC4. GA release is planned for next week.

Thanks.

[Bernd Götz]

Hello Simon, GA wasn't released this week, I guess. I could not find any 6.3 RCx versions for download, are they publicly available? Thanks.

Best regards,

Bernd

[Simon Brandhof]

Hi, 

6.4 GA will be released on Tuesday. Meanwhile you can find the latest RC here: https://bintray.com/sonarsource/Distribution/SonarQube/6.3-RC4#files/sonarqube

Regards

[Simon Brandhof]

Typo: next release is 6.3 GA.

Thanks! I can confirm that the issue is gone in 6.3 RC4.

[Simon Brandhof]

Good news. Thanks for the follow up.
