Hi, we are getting this error while analyzing java code with sonar scanner, i tried by disabling all rules but still facing same issue. Could any one help help me to fix this and thanks for your help in advance. ```auto ERROR: A stack overflow error occurred while analyzing file:

Hi, Could you provide your version of SonarQube, and a reproducer file?   Thx, Ann ---

Hi @srujanch, @ganncamp, We encountered the same error. Maybe I can provide some additional data points from our own experience: - SonarQube version: 8.4.2 - SonarJava version: 6.5.1 I noticed this started happening when we enabled the **java:S5790** rule to align our quality profile with the default profile. But note that I’m not confident it’s only this particular rule - just the first one that started causing the issue. In our case, the affected file was a _huge_ generated unit test file (6k LoC, most of it in a `static {}` block). I did some basic binary search by removing parts of the file to see if a particular block causes the error, but it looks like it’s the sheer size of the file. We excluded that file from the analysis since it doesn’t make sense to analyze a generated file, so it’s not really a critical problem for us. ---

Hey @srujanch, @sandro-h, It is likely that our parser is not able to create the AST, due to the amount of LOC in some generated statements. Can you try to increase the stack size allowed by your analysis? It fixed similar issues in the past. > [@java.lang.StackOverflowError is thrown when maven sonar:sonar is running](https://community.sonarsource.com/t/java-lang-stackoverflowerror-is-thrown-when-maven-sonar-sonar-is-running/26429/2): > > Solved, limiting heap and increasing stack size helped: MAVEN\_OPTS: -Xmx3g -Xss2m Cheers, Michael ---

Hi @srujanch@Michael , I am facing this same issue even with Sonar qube 8.9 LTS & scanner 3.9.0.2155 I tried increasing memory as well , still it didn’t help . Any suggestions ? Thanks, Gopal ---
