JRE的较新版本不加载音库，但旧版本不 [英] Newer version of JRE doesn't load soundbank but older version does

问题描述

我有以下的code，它会尝试加载音库。我和JRE 03年6月1日和43年1月6日测试在Windows 7中的code。老版本的JRE（03年6月1日）的正常工作，但新版本中会抛出异常。这是怎么回事？

I have the following code that tries to load a soundbank. I've tested the code on Windows 7 with JRE 1.6.03 and 1.6.43. The old version of the JRE (1.6.03) works fine but the new version throws an exception. What's going on?

public Main() {
    try {
        Synthesizer synth = MidiSystem.getSynthesizer();
        synth.open();
        BufferedInputStream soundBankStream = new BufferedInputStream(
                getClass().getClassLoader().getResourceAsStream(
                        "soundbank.gm"));
        synth.loadAllInstruments(MidiSystem.getSoundbank(soundBankStream));
    } catch (MidiUnavailableException e) {
        e.printStackTrace();
    } catch (InvalidMidiDataException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }
}

您可以从这里下载的音库：<一href=\"http://www.oracle.com/technetwork/java/soundbanks-135798.html\">http://www.oracle.com/technetwork/java/soundbanks-135798.html

推荐答案

我一直有同样的问题，从我发现，JAVA的最新版本（1.7+），通用汽车音库不再支持

I have been having the same problem, and from what I have found, the latest versions of java (1.7+), the GM soundbanks are no longer supported

的http://www.oracle.com/technetwork/java/javase/compatibility-417013.html#incompatibilities

在Java Sound包的软件合成实现已被替换的开源版本。由于置换，其特点如下只好作罢：
  GM音库的支持，
  RMF文件播放的支持，
  在Linux平台上OSS（开放声音系统）的支持。
  新合成的实施支持DLS和音色库（SF2）格式的音库。

The software synthesizer implementation in the Java Sound package has been replaced with an open sourced version. Due to the replacement, the following features were dropped: GM soundbank support, RMF file playback support, OSS (Open Sound System) support on the Linux platform. The new synthesizer implementation supports soundbanks in DLS and SoundFont (SF2) formats.

，因为它说，它支持DLS和SF2 Soundbank中的格式（我与你在做什么，试着和它的工作）。看看在互联网这些文件，如在这里：

As it says, it supports the DLS and SF2 Soundbank formats (which I tried with what you were doing and it worked). Have a look around on the internet for these files such as here: http://www.ronimusic.com/smp_ios_dls_files.htm
