It looks like a bug in IcedTea PulseAudio provider implementation. You can file a bug report at http://icedtea.classpath.org/

Hello there! We have been using IcedTea/PulseAudio for some load tests for playing audio and came across a memory leak which we are now searching. Test setup: Create a Clip object of some arbitrary sound file, play it once, then close it – rinse and repeat, many times. After a few hours we came across an out of memory exception. Analysing the memory dump we found that all Clip objects were still active, with the garbage collector root being "JNI Global" for the stream objects that each Clip is creating. See attached image showing a selected Clip object. The clip itself was kept alive through callback interfaces to Stream, but isOpen=false proves that close() was called. I then proceeded to go through the code of icedtea6-1.9.13 and came across the Stream.java / org_classpath_icedtea_pulseaudio_Stream.c pair. The native function for native_pa_stream_new() does the call to NewGlobalRef() to keep the Stream object alive – presumably for the callbacks. But I didn't find the complementary call to DeleteGlobalRef(). I'd assume this should be done in native_pa_stream_unref(), as this one is the last to be called from PulseAudioDataLine.close() -> Stream.free() . How is the stream expected to be released properly? Are we missing something or is this leak genuine? For now we will modify our code to keep and reuse the Clip objects, but it would be good to know the root cause.
