Only if you're stuck with bytecode rather than source.

But even then, you don't need an "ieee floating point package", just
converstion from IEEE to VAX.  (And back, if you want to generate
bytecode compatible with IEEE JVMs.)

s/write and// - there's no reason to assume that using VAX floats means
that you will _write_ all your own code.  Even aside from that, there's
plenty of java code - even bytecode - that doesn't even use floats.

You consider C++ equivalent to Java if you're working with source?  I
sure don't.
