I was able to get something non-trivial to cross compile, but when I ran<br>
NestedVM on it, I got this exception:<br>
<br>

I googled a bit and found that it's been hit before, and there's not really<br>
a workaround. The difference is that that code used several libraries, mine<br>
uses just the standard ones. When I ran nm on it, it only had 4325<br>
lines of output (I assume it's one line per symbol)--far from the 64k limit.<br>
I put a System.out.println at ClassFileCompiler.java:179, and symbols only<br>
has ~4325 elements.<br>
<br>
Any ideas?<br>
