Using A Sun based Javac to compile rt-closed.jar different from using gcj

[Michael Franz]

Hi,

It has taken a few days but I have figured out why my rt-closed.jar is
missing a bunch of classes.

I am building on OS X and using either Apple's JKD or an older version of
OpenJDK.  It seems that on Fedora the creation of the rt-closed.jar using
gcj to compile the sources in rt/ .  The class files are created in lib/rt,
this is then jar'ed to create rt-closed.jar.  It seems that gcj (and ecj)
will put classes that are reference (directly/indirectly) by the classes it
compile into the output directory.  This explains why lib/rt has class files
that are not in rt.  Since Apple's JDK or OpenJDK itself do not do this the
rt-closed.jar is missing classes that are assumed to be there later causing
the bootstrap process to fail.

Is this functionality of gcj and ecj an undocumented switch in OpenJDK?
