To avoid that an imported Library override a specific Java method

Question

Hypotesis:

• I import inside my project, in Netbeans, the external library "Tritonus_remaining_0.3.6" (I import the compiled .jar file)
• I need to use the mehod "javax.sound.sampled.AudioSystem.getAudioInputStream(MY_AudioFormat__Target, MY_audio_input_stream__Source)"
• Tritonus override this method "javax.sound.sampled.AudioSystem.getAudioInputStream()" ; I see it because in some cases, when I invoke this javax method, I get an exception on this method indicates the problem in "org.tritonus....."

Target:

• In same cases I DON'T want that Tritonus override this "javax.sound.sampled.AudioSystem.getAudioInputStream()" and I want to use the original method of javax package.

Question:

• How to do it, considering that I need that Tritonus library in other parts of my project, then I need to import it?
