Hey there,
We recently upgraded SonarJava from 4.10 to 4.13 and ran into the following analysis error for some projects:
I was able to trace it to the use of the commons-lang library in that code. The project itself uses a somewhat up-to-date version of commons-lang, but through transitive dependencies and the way we generate the sonar.properties file for the runner, a commons-lang version 2.1 makes its way into the list of libraries for sonar to use.
If I manually exclude 2.1 from the list, the analysis passes.
commons-lang 2.1 was compiled for Java 1.1. Starting with commons-lang 2.4, it is compiled for Java 1.2 and onward.
Since the analysis passes with 2.4+, it seems to me that the scan is no longer able to correctly handle Java 1.1 bytecode.
As a workaround, I can simply exclude these old commons-lang versions from the analysis.
Long story short: I wanted to clarify if Java 1.1 bytecode is officially no longer supported or if that's a bug that snuck in? I wasn't able to find anything about that in the documentation.
Thanks & cheers,
Sandro

Hi,
Cheers,
Thanks a lot for reporting this.
The issue seems to be related to bytecode analysis. Now to jump to the conclusion that this is about unsupported version 1.1 is a bit fast. The implementation of dataflow analysis on bytecode was done on a limited set of methods. As per apache commons-lang : Validate#notEmpty Validate#notNull and StringUtils#isEmpty #isNotEmpty #isBlank #isNotBlank
So could you share the piece of code causing the issue (privately eventually) or at least pointing out which one of those method (or any other) from apache commons-lang you are using in the file making the analysis fail ?
That would help to narrow down the method causing the problem and try to reproduce what is going on and from there determine if it is a problem with instructions from java 1.1 compiler (which I doubt) or, more likely, a not yet supported instruction in our bytecode analyser or (even more likely given the stacktrace) a bug in our CFG built from the bytecode.
Thanks !

Hi Sandro,
I have the same problem, how did you exclude commons-lang 2.1 from SonarQube classpath? I tried to exclude the jar with sonar.exclusions property, but it's meant for sources, not binaries.
Cheers,
Vincent

Hi,
Thanks for the reporting this.
Getting this investigated, this is clearly a bug in our CFG construction on bytecode : https://jira.sonarsource.com/browse/SONARJAVA-2461
As this is failing the analysis we plan to deliver next version a bit earlier than what was our plan before. So I am working to fix this one and we'll send a request for feedback containing the fix beginning of next week.
In the meantime, as a workaround, I can only encourage you to upgrade this library.
Cheers,

Hey Vincent, Sandro,
A small message just to tell you that we are starting RFF for SonarJava 4.14, which contains the fix for this.
Feel free to try it here.
Cheers,
Michael

Hi guys,
First of all, sorry for the slow response when you were asking for more feedback. I need to improve the notification settings for this account :)
I just tried the 4.14 RC on one of our failing projects and it no longer produces the NullpointerException. So looks good from my point of view!
Vincent: I suppose it won't be necessary once 4.14 is out, but for completeness: as some of our older projects use Ant, we compute the sonar.java.libraries property ourselves and simply excluded those troublesome libraries there. See also https://docs.sonarqube.org/display/PLUG/Java+Plugin+and+Bytecode.
Thanks for the quick fix & cheers,
Sandro

Hi Vincent,
Thanks for getting back on this. I managed to reproduce the issue. So my bad seems I screwed up my testing on that topic.
Working towards a fix.

Hi Vincent,
A fix has been made available in the RFF thread : https://groups.google.com/forum/?utm_medium=email&utm_source=footer#!topic/sonarqube/jAvEU2Ohqpk
Thanks again for getting back to us on that one and sorry for the first partial fix.
Cheers,

Now I got OOM errors and my process is killed by Linux kernel after having analyzed only between 40 and 80 files.
Is there a possible memory leak in the recent commits?

Hi Vincent,
well, as per the last modification and as per what we delivered so far we are not aware of anything. So let's get this investigation from the start : can you share a stacktrace ? what is happening exactly ?
Can you share the project or the file(s) causing trouble ?
Cheers,

Hello,
No I don't have any stacktrace. The process is killed randomly, but for every analysis (I tried a dozen times and increased the allowed memory):

I'm on RHEL7 up-to-date. I will try tomorrow an analysis with an older version of the plugin which worked on my platform to be sure it comes from this version.

Hello,
The problem also occurs with a previous version which worked, so it might be due to a recent RHEL update.

Hi Vincent,
good to know (for us ;) ) Let us know if you pinpoint back the issue to SonarJava.
Cheers,
