Details:

This example doesn't work on Android:

 (import (only (rnrs hashtables) string-hash))
 (string-hash "foo")


The log contains this message:

I/dalvikvm(10717): Could not find method java.lang.CharSequence.hashCode,
referenced from method kawa.lib.rnrs.hashtables.stringHash


The problem seems to be caused by this:

  1: invokeinterface (1 args) <InterfaceMethod java.lang.CharSequence.hashCode
()int>


CharSequence is an interface that doesn't epxlicitly define hashCode
but hashCode is defined on Object.  I guess Kawa could just as well
use invokevirtual Object#hashCode.
