考虑以下类：

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"; 
}
}

这编译得很好，但是在使用 SonarQube 进行分析时，我遇到了一个Unable to create symbol table for : <Class>错误（下面的完整堆栈跟踪）。

我正在使用 SonarQube 5.6.3，这发生在命令行 (SonarQube Scanner 2.7) 以及 Eclipse (SonarLint 2.2.1) 中。

PS：作为参考，这是我得到的完整堆栈跟踪：

如果我的感觉是正确的，您将面临这个已在即将发布的 SonarQube Java 插件 4.2.1 版本中修复的错误：https ://jira.sonarsource.com/browse/SONARJAVA-1839 。事实上，SonarLint 中还没有。
