次のクラスを検討してください。
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";
}
}
これは正常にコンパイルされますが、SonarQube で分析するとUnable to create symbol table for : <Class>エラーが発生します (以下の完全なスタック トレース)。
私はSonarQube 5.6.3を使用しています。これは、コマンドライン(SonarQube Scanner 2.7)とEclipse(SonarLint 2.2.1)で発生します。
PS: 参考までに、これは私が取得している完全なスタック トレースです。
