This bug shows up in SQE testing as well.
Simply change sample rate while a clip is playing and the application will crash and the message regarding "An unexpected exception has been detected in native code outside the VM" is displayed.
This bug is a block to reliability testing.

orig synopsis:  "Bug #4281181 test program doesn't work"

19 Dec 2000, eval1127@eng -- once the test program is altered
to run without the noted exception, it fails with an
"unexpected exception...outside the VM" 
(under both 1.3.0 and merlin-beta45)
Thus, this may be a runtime/HS issue, not a classes_sound issue, per se
------------------

user's submission:

java version "1.3.0"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.0-C)
Java HotSpot(TM) Client VM (build 1.3.0-C, mixed mode)

I had some problems with the SAMPLE_RATE control, so I entered the sample
program at the bottom of bug #4281181.  The sample program does not work.
Specifically, it fails with this stack trace:

java.lang.IllegalArgumentException: This method should not have been invoked!
        at com.sun.media.sound.MixerClip.implOpen(Unknown Source)
        at com.sun.media.sound.AbstractDataLine.open(Unknown Source)
        at com.sun.media.sound.AbstractDataLine.open(Unknown Source)
        at SoundTest.main(SoundTest.java:24)

The problem is that the Clip.open() method is being called with no parameters.
It should read "Clip.open(ais)".

I am reporting this as a bug because the error message is not helpful, even
though the semantics of the test program are wrong.  Also, it is sort of a
"metabug" since the bug database has a bug :)

---------------

19 Dec 2000, eval1127@eng -- with 1.3.0, using the "new test" at the
bottom of bug # 42811 (with "Bug4281181" substituted for
"SoundTest" classname):

java.lang.IllegalArgumentException: This method should not have been invoked!
        at com.sun.media.sound.MixerClip.implOpen(MixerClip.java:457)
        at com.sun.media.sound.AbstractDataLine.open(AbstractDataLine.java:87)
        at com.sun.media.sound.AbstractDataLine.open(AbstractDataLine.java:383)
        at Bug4281181.main(Bug4281181.java:21)

The reason this compiles is because open() is valid in superinterface Line.

Replacing open() with open(ais) plays the sound, but then aborts with:

# Problematic Thread: prio=10 tid=0x1c5930 nid=0xc runnable

-------------

With merlin(1.4) beta 45, the .wav plays longer, but the program still aborts:
