Java 8在JBoss EAP 6.4遭遇UnsupportedAudioFileException问题求助

问题背景 #

使用Java 8开发应用，接收Base64格式的.wav音频文件并转换为PCM_SIGNED格式，本地运行正常，但部署到JBoss EAP 6.4时抛出UnsupportedAudioFileException。

报错核心代码 #

源音频文件属性 #

手动将Base64转换为.wav文件后，文件属性如下：

Encoding       : PCM_SIGNED  
Sample Rate    : 40000.0 Hz  
Sample Size    : 16 bits  
Channels       : 1  
Frame Size     : 2 bytes  
Frame Rate     : 40000.0 frames/second  
Big Endian     : false  

尝试的替代方案及问题 #

尝试先将Base64转换为物理.wav文件再处理，代码如下：

File file = new File(sourceFilePath);
InputStream inputStream = new BufferedInputStream(new FileInputStream(file));

if (!inputStream.markSupported()) {
    return;
}

AudioInputStream audioInputStream = AudioSystem.getAudioInputStream(inputStream);
AudioFormat sourceFormat = audioInputStream.getFormat();

AudioFormat targetFormat = new AudioFormat(
        AudioFormat.Encoding.ALAW,
        8000,
        8,
        sourceFormat.getChannels(),
        1,
        8000,
        false
);

AudioInputStream convertedAudioInputStream = AudioSystem.getAudioInputStream(targetFormat, audioInputStream);

AudioSystem.write(convertedAudioInputStream, AudioFileFormat.Type.WAVE, new File(destinationFilePath));

inputStream.close();
audioInputStream.close();
convertedAudioInputStream.close();

但在AudioInputStream audioInputStream = AudioSystem.getAudioInputStream(inputStream);一行仍报错：

javax.sound.sampled.UnsupportedAudioFileException: could not get audio input stream from input file
    at javax.sound.sampled.AudioSystem.getAudioInputStream(AudioSystem.java:1189)
    at com.assistt.voicecloneservice.service.AudioConverter.convertBase64ToPcmSigned(AudioConverter.java:34)
    ...

提问 #

需要检查哪些要点，或尝试哪些替代方案来解决该问题？在JBoss环境中处理音频文件是否需要特殊配置？
