Application hangs on exit with v2.1.0

[curtisporter1]

A standalone application built with ApplicationInsights-Java hangs on exit. There is a thread pool (pool-1-thread-1) that is not shut down, and it prevents the application from exiting. This does not occur with version 2.0.2.

Attached is a trivial program that demonstrates the problem.

Thank you for bringing this to our attention. We're investigating the issue.

I found the issue and have a PR for it. In the meantime, @curtisporter1 , if this is blocking you, there is a workaround:

As the last statement in your main method, add SDKShutdownActivity.INSTANCE.stopAll();. This will stop all the threads in the SDK, including the one in question. If you have the SDKLogger enabled, you may see some exceptions, but this is expected.

This fix will ship in the next release.
