Hotspot (JDK1.3.0fcsC, JDK1.4.0beta-b24, solaris) crashes during
startup when redefined java.lang.Object class precedes standard
Object class in the bootclasspath. Classic VM reports an exception
under the same conditions. Inserting incorrect core classes in the
bootclasspath is not good practice but JVM should be stable enough
to track such issues (like classic VM does).
