NullPointerException in web service engine while displaying a rule

[sebastie...@neomades.com]

Hi everyone,

I'm using SonarQube version 5.2 ad I'm experiencing a problem when I try to display the details of a rule: a tooltip indicates that the operation failed and there is a NullPointerException in the logs.

Steps to reproduce the bug:
 - select "Quality Profiles"
 - select "Sonar way"
 - click on the number of active rules to display the list of rules
 - the first rule is "Anon Inner Length"; click on this rule

Result: a red tooltip says "Failed".

I've displayed several other rules without any problem.

In sonar.log, the following error is reported:
2015.11.17 12:38:35 ERROR web[o.s.s.w.WebServiceEngine] Fail to process request http://<host>:9000/api/rules/show?key=checkstyle%3Acom.puppycrawl.tools.checkstyle.checks.sizes.AnonInnerLengthCheck&actives=true

I've truncated the stack trace because it is quite long but I can provide the full stack trace if necessary.

Please tell me if more information is needed.

Hi,

I've found a workaround.
I had the same error as above while displaying the list of rules of one of the quality profiles. I made a copy of this profile and then removed it (keeping the copy) and the problem has disappeared. I can now display the "Anon Inner Length" rule without any error.
