The method DataLine.getFramePosition() returns an int value. This value, however, has a very limited range and will overflow (wrap-around) after 2 billion frames -- about 13:20 hours at CD quality, and even shorter for higher sample rates. During the following 13 hours, getFramePosition will report increasing negative numbers, until 0 is reached again.

One objective of Java Sound in Tiger is to stabilize the implementation and make it usable for long-term usage found in security software, telco usage, VoIP, and streaming audio like Internet Radio. This API flaw is a possible stopper for adoption of Java Sound for such applications.

The suggested fix is to add a method to interface DataLine:
    long getLongFramePosition()

This API caused failure of the new reliability tests (see bug #5047795). The implementation was changed to operate on longs internally, so that a fix for this bug just means to expose the already internally existing method.
