Call to 'Thread.start()' during object construction

Reports calls to start() on java.lang.Thread or any of its subclasses during object construction.

While occasionally useful, such constructs should be avoided due to inheritance issues. Subclasses of a class that launches a thread during the object construction will not have finished any initialization logic of their own before the thread has launched.

This inspection does not report if the class that starts a thread is declared final.

Example:

class MyThread extends Thread { MyThread() { start(); } }
