Hello, We are using 8.2 Community Edition with all up to date plugins. We are very experienced with SQ having used it since version 3. For a long time we have been noticing old issues raised again as new issues and have tried for a long time to understand the causes. We have researched the expla…

Hi Ann, Thanks for this. Re: 2 We increased the Closed Issues expiry period around 6 months ago from the 30 days to 365 days so would expect to be seeing many, many closed issues from this project which has a large team working on it. We still believe something odd is going on here with this pro…

Hi Ann, One other question… Am I right in thinking that the process of reflagging issues is part of the way Sonar guarantees it reports all issues – it can be thought of as a ‘catch all the rest’ technique when it can’t match an issue found on the new scan with one found on the previous scan (seem…

Hi Will, [image] Will: We are using 8.2 Community Edition [image] Will: Re: 2 We increased the Closed Issues expiry period around 6 months ago from the 30 days to 365 days Weeell… You must have made that config change before the upgrade to 8.2 because the cleanout period got hard-cod…

Hi Ann, We appreciated your answers to the above which helped immensely. Thank-you and apologies for not replying with thanks in May. We have discovered this behaviour happening again on a feature branch analysis for the same Java project discussed above. To test this, here is what we did: Crea…

Hi Will, In both image sets you’ve shown me an issues graph that apparently has the same number of issues in all analyses. I.e. I see perfectly parallel, horizontal stripes in both images. [image] Will: To test this, here is what we did: Created 2 branches from the same source branch with id…

Hi Ann, Thanks for getting back to me. The zip had 6 images for each of the two branches. The counts are different and the new issues are showing when there have been no code or platform changes. The reason those graphs look horizontal is due to the scale - there are 75,000 issues and less than 1…

Hi Will, I see 6 images total: Issues, Activity, and Overview for A and for B. [image] Will: Although the total number of issues is the same in each project (75,164), the number of new issues since the first analysis are different in each project (969 in one, 765 in another), Without having…

Hi Ann, Thanks for getting back to me again. The behaviour is quite easy to reproduce with this analysis. Simply reanalysing without changing code seems to produce random new issues each time. Given this is a very large project with >70,000 unresolved issues then perhaps tolerances are exceeded …

Hi Will, [image] Will: when we remove the CheckStyle plugin the behaviour stops This is very interesting! It still makes me wonder how/why the Checkstyle issues aren’t meeting the old-issue match criteria, but that’s really out of our hands. If you can narrow this down to being a Checkstyle …

Hi Ann, Running again it picked up two issues this time… again with no code changes. They are in different code files and are from different plugins: findbugs:NP_GUARANTEED_DEREF: Null value is guaranteed to be dereferenced java:S2259 : Null pointers should not be dereferenced A copied identica…

Hi Ann,

Have you any update or can refer us to anyone to discuss this, provide additional information.

I do notice others on this site that seem to be finding similar java / 8.2 behaviour, such as this one.

Thanks

Will
