C Native code within Java application fails under Solaris 2.5.1 ok under 2.5

Customer has developed a piece of java code which includes a piece of C native code. The C native code attempts to open and operate upon the audio device. The whole intent is to be able to open and ultimately use the audio device for recording and playback. This example just tries to open audio.

Note that the c code will run on both 2.5 and 2.5.1 and that the java example shown here and indicated to be problematic on a 2.5.1 system will run quite well on a 2.5 system.

I have tried both recompiling on the 2.5.1 system which has java 1.0 installed as well as trying the binary from the 2.5 system. No differences in operation were noted.

> I got a chance to try this out this afternoon. I first tried without
> recompiling and then tried again after recompiling on a 2.5.1. system (latest
> kernel patch).
