conceivable, just barely, that somebody might write a Java

JVM would run out of memory trying to compile it.
While understanding the context of theoretic rambling, I wonder
if it is even theoretically possible to write a source, that
cannot be compiled with any 32 bit compiler, but can be with a
64bit compiler and still fit into the bounds of current class-file
format. (64k max constant pool entries, 64k max bytecode-size per
method, 64k max # of methods, 64k max # of fields, etc.)
Ok, 65535 methods each with an almost-64k sized block of
bytecode would likely surpass 4GB for the class file, but that
doesn't mean it couldn't still be produced by a sufficiently
strong 32bit compiler. (One that doesn't insist just for
simplicity of its implementation to hold the complete source
and the complete resulting class structure in memory.)
