Sound Process Error
I'm currently developing a software using JavaTM Sound API which plays a numeric sound inputed from numeric keys.
The Software finds numeric wav file matches the number inputed from numeric key and plays it in order.
I have wav files plays "0" to "999" numeric sound , "thousands" and "ten thousands".
For example if "1300" is inputed from numeric key, it finds "1" wav file, "thousand" wav file and "300" wav file to play "1300".
If another numeric key is pressed while playing sound, it quit playing current sound and plays the sound of inputed sound.
There are no problem if the key is pressed slowly, however, if the key is pressed rapidly, I get hs_err_pid2240.log and the process is terminated.
Here is the part of hs_err_pid2240.log.

Just little note, When the key is pressed, wav file name is inserted into "List" and "addSound" method is called.
"addSound" method can be used by multiple thread.
I'm using 1.5.0_06-b05 JRE on WindowsXP.
I have spent lots of time to solve this problem. But still not found a solution to it.
Could please anyone help me?
Thank you.
