SonarQube error: "Unable to create symbol table for "

Question

consider the following class:

public class SqAnalysisTest {
public void method () {
    Collection<Reader> readers = new ArrayList<> ();
    readers.add (SqAnalysisTest::readString);
}

@FunctionalInterface
public static interface Reader {
    Object read (ByteBuffer buffer);
}

public static String readString (ByteBuffer buffer) {
    /* read string from buffer and return */
    return "a string"; 
}
}

This compiles fine, but when analyzing with SonarQube I'm getting a Unable to create symbol table for : <Class> error (full stacktrace below).

I'm using SonarQube 5.6.3, this happens on the command line (SonarQube Scanner 2.7) as well as in Eclipse (SonarLint 2.2.1).

PS: For reference, this is the full stack trace I'm getting:

If my feeling is correct you're facing this bug which has been fixed in the upcoming 4.2.1 version of the SonarQube Java Plugin : https://jira.sonarsource.com/browse/SONARJAVA-1839. And indeed not yet available in SonarLint.

Thanks for your answer. However, I have the 4.2 version of the Java plugin installed. Anyways, I just realized that the official place to report bugs is the google group, should I move the discussion there? – JohannesR Oct 10 '16 at 07:24
Hi @JohannesR, I've updated my answer because in fact the issue is due to https://jira.sonarsource.com/browse/SONARJAVA-1839 which has been fixed but not yet available. Version 4.2.1 should be released this week. – Freddy - SonarSource Team Oct 10 '16 at 07:32
Ah, ok. I'll test 4.2.1 when it's available. Thanks! – JohannesR Oct 10 '16 at 08:17
