Description
I am attaching a test application that demonstrates this problem.

> java JavaSoundStreamPlayer

Load a sampled audio file, then try this sequence:
- Open
- Start (sound starts playing)
- Stop  (sound stops)
- Close
- Open
- Start (no sound is heard)

Querying Status shows that the SourceDataLine being used returns
isOpen()    - true
isRunning() - false
isActive()  - false
after Start is called the second time.

EVALUATION ###@###.### 2000-01-13 This is serious, but too late to get a fix into Kestrel RC1. Committing this to Merlin for now. michael.bundschuh@Eng 2000-08-25 No resource to fix for ladybird. Committing for merlin. ###@###.### 2002-07-18 Verified the existence of the bug. The SourceDataLine should throw LineUnavailableException, as it is stated in the open method: "Note that some lines, once closed, cannot be reopened. Attempts to reopen such a line will always result in a LineUnavailableException." ###@###.### 2002-07-18 Found the problem in MixerSourceLine, the implStarted variable wasn't reset to false upon close(). Fixed for mantis.
