public class testSonarJava {
private static final ThreadLocal<List<String>[]> foo = new ThreadLocal<List<String>[]>();
public void testSonarPASS() {
foo.set(new ArrayList[1]);
List<String>[] lists = foo.get();
lists[0] = null;
}
public void testSonarFAIL() {
foo.set(new ArrayList[1]);
foo.get()[0] = null;
}
}
When trying to analyze this class, I get analysis error on testSonarFAIL method: Unexpected expression METHOD_INVOCATION
testSonarPASS is analyzed without any issues.
hello @tvasenin,
which version of SonarJava plugin do you use? I am not able to reproduce the issue with the latest version. Also, please post the log including full stacktrace.
I have the same problem.
SonarJava: 5.14 (build 18788) installed
This is the sample class:
import org.apache.commons.lang3.tuple.ImmutableTriple;
import org.apache.commons.lang3.tuple.Triple;
public class NewClass
{
public void getHierarchiaElemek()
{
SubClass sc = new SubClass();
sc.getVar()[0] = new ImmutableTriple<String, Integer, Integer>("", 1, 1);
}
public class SubClass {
Triple[] var = new Triple[1];
public Triple[] getVar()
{
return var;
}
}
}

Thanks a lot for the self-contained reproducer!
I have been able to reproduce it on my machine with latest released Java plugin.
Here is the ticket to track the issue: SONARJAVA-3185
Cheers,
