Below is a section of logcat which contains the message I'm occasionally seeing: Queue's awaitRelease() has been interrupted abruptly while it wasn't released byte release() method. The "byte" seems to be a typo. Searching the project for the string "byte release" doesn't find anything.
Where is this message coming from, and what does it mean? The program appears to work OK.

it comes from QueueSemaphore.java. This spelling mistake has been fixed already in master.
It is nothing you should be worried about, the state of the library is cleaned up correctly. It happened because your DescriptorWriteOperation was blocking the semaphore when it was "abruptly interrupted" by a disconnect operation.
