Virtual function call from constructor

[Mike Schilling]

No; that's the Java language. If Object's constructor
ultimately chained from a PrintStream constructor were to
evaluate `this instanceof PrintStream' the result would be
`true', on every JVM. (Object's constructor has no reason
to do any such thing, but that's another matter.)

The question was "Does Object even have a nontrivial constructor?" That is,
whether its constructor contain any code. As far as I know, that can differ
between implementations.

You can rewrite the Object constructor using instrumentation, so I
believe all implementation should allow the Object constructor to
contain real Java code.
