Hi there =97

I was looking for a way to get the process ID of a process that gets starte=
d by the DefaultExecutor. From looking at the javadoc, there=92s no built-i=
n way to do it.

Google recommends that I create a subclass of DefaultExecutor that override=
s the launch() method, such that the Process it returns is interrogated for=
 the PID. DefaultExecutor isn=92t final and launch() is protected, so in pr=
inciple this can be done.

However:

The only public constructor for DefaultExecutor is deprecated. The non-depr=
ecated method to instantiate a DefaultExecutor is to use the DefaultExecuto=
r builder, but AFAICT there=92s no way to get this builder to return a Defa=
ultExecutor subclass. I could subclass the DefaultExecutor builder, but the=
 DefaultExecutor builder uses a package-private DefaultExecutor constructor=
, so my subclass of DefaultExecutor builder can=92t use that constructor.

In a pinch, I could imagine giving my subclass its own constructor that emu=
lates the package-private one in DefaultExecutor. Unfortunately, this also =
won=92t work: all the instance variables are private and there are no prote=
cted setters for them.

It seems like the intent is there to allow users to subclass DefaultExecuto=
r, but in practice the only way to do it appears to be the deprecated publi=
c constructor. Am I missing something?

Is there an easier way to get the PID from a DefaultExecutor?

Thanks,
-PT
