I believe the behavior of this method may contradicts its javadoc, which
says that
> If the argument does **not** start with '-' or is **not** the name of a
Locator launcher command, then the value is presumed to be the member name for
the Locator in GemFire.
Whereas the actual implementation seems to find values which **are** the
name of a Locator launcher command. I would guess that the javadoc is correct
about the intended behavior.
<hr>
P.S. I can't resist writing this in a declarative style with streams :)
```
protected void parseMemberName(final String... args) {
if (args == null) return;
Arrays.stream(args)
.filter(arg -> !(arg.startsWith(OPTION_PREFIX) ||
Command.isCommand(arg)))
.findFirst()
.ifPresent(this::setMemberName);
}
```
