import javax.sound.midi.*;

MidiDevice.Info[] infos = MidiSystem.getMidiDeviceInfo();

MidiDevice device;

try {

  device = MidiSystem.getMidiDevice(infos[11]);

} catch (MidiUnavailableException e) {}

for (int i = 0; i < infos.length; i++) {

  print(infos[i]);

}

That code prints the following:

However, every single one of those devices, if it is not in the try, catch block that discards MidiUnavailableException, will throw just that exception.  Yet none of my devices should be in use for anything, so I'm not sure why all of them throw this error.  Any thoughts?

import javax.sound.midi.*;

MidiDevice.Info[] infos = MidiSystem.getMidiDeviceInfo();

MidiDevice device;

try {

  device = MidiSystem.getMidiDevice(infos[11]);

} catch (MidiUnavailableException e) {

  print("THIS WILL NEVER, EVER PRINT, EVER");

}

The catch block never executes, even though I know that particular exception is encountered (in fact it's encountered for every single one of my midi devices when I iterate through "infos" - but that's another topic).  If I change the line inside the catch block to throw a general exception, it executes.  But printing, assigning values to variables, etc. never execute inside the catch block.
