Findbugs hangs for a long time without producing logs and then exits with EmptyStackException error

[darferrari]

Issue Description

Hi, I'm having a issue with Findbugs: it has been a while since I ran the last sonar analysis using findbugs (on March 2021). The last time I used the plugin would elapse 20 minutes to produce the report to be sent to Sonarqube. I'm using the maven plugin for sonar-scanner and nothing has changed since then except the code to review. The main issue is that this is a multi-module project with cascade-style dependencies (the module after depends on the previous one) with millions lines of code. In particular, findbugs hangs on one of the biggest modules for more than a hour (sometimes even 5 hours)

[INFO] Loading findbugs plugin: /opt/jenkins/workspace/***/target/sonar/findbugs/sb-contrib.jar
[INFO] Loading findbugs plugin: /opt/jenkins/workspace/***/target/sonar/findbugs/findsecbugs-plugin.jar
[INFO] Findbugs output report: /opt/jenkins/workspace/***/findbugs-result.xml

It then interrupts the execution with an error, here there is the complete StackTrace that maven gave me using the -e switch:

Before this error occurred, I stumbled across two errors, one given by the fact that there wasn't enough Java Heap space, one regarding the TimeoutException (extended the timeout to an unrealistic time, 6 hours)
I already have JVM heap memory expanded to min 500 MB and max 2048 MB and tried to play with Findbugs settings on the Sonarqube server, using minimal effort to find bugs and so on.
The issue seems related to the size of the module which contains a lot of dependencies and several java files, 1929.
The maven command I use to issue the analysis is the following:

mvn sonar:sonar -Dsonar.projectName=*** -e

Have you ever stumbled upon a scenario like that?

Component	Version
SonarQube	8.5.1.38104
Sonar-FindBugs	4.2.0
Maven	3.6.3
Java	8

Hello, have you found a solution ? it seeems I have a similar problem with sonarqube scanner on jenkins since I upgraded from sonar 7.9 to 8.9 LTS.

Hello christopheroger, I found a workaround by executing the scan in -X mode (debug) and forcing the execution of the scanner using one thread (it is not thread safe). By doing that, I was able to identify the java and class file that was causing the script to fail (it was stuck for an entire hour at that file). Basically what was happening was that the java file would explode the graph creation. I think that it was a memory error, 3 GB of heap didn't help.
