このテスト:
import java.util.zip.Deflater;
import org.apache.mina.core.buffer.IoBuffer;
import org.apache.mina.filter.support.Zlib;
import org.junit.*;
public class ZlibTest {
private Deflater deflater = null;
private Zlib inflater = null;
@Before
public void setUp() throws Exception {
deflater = new Deflater(Deflater.BEST_COMPRESSION);
deflater.setStrategy(Deflater.DEFAULT_STRATEGY);
inflater = new Zlib(Zlib.COMPRESSION_MAX, Zlib.MODE_INFLATER);
}
@Test
public void testInflate() throws Exception {
byte[] compressed = new byte[14];
deflater.setInput(new byte[] {1});
deflater.finish();
int bytesCompressed = deflater.deflate(compressed);
IoBuffer compressedBuffer = IoBuffer.wrap(compressed, 0, bytesCompressed);
System.out.println(compressedBuffer);
IoBuffer byteUncompressed = inflater.inflate(compressedBuffer);
}
}
失敗します:

ここで何が問題になっていますか?
更新:追加した場合
case JZlib.Z_STREAM_END:
Zlib.javaの139行目までは、正常にデコードされます。
