Daemon threads act as background tasks and do not prevent the JVM from
shutdown normally. JPype automatically attaches any threads that call
Java resources as daemon threads. To convert a daemon thread to a user
thread, the thread must first be detached.
Raises:
RuntimeError: If the JVM is not running.
