Re: [Jscheme-user] errors in jscheme with java-1.5-beta

[Ken A. <kan...@bb...>]

This looks like quasi quote is ultimately invoking  (.append stringBuffer ...)
and we try to invoke a method on java.lang.AbstractStringBuffer .

Can you do a simple test, like:

(define x 4)
{x + 3 = [(x + 3)]}

This should cause the problem.  This might be a method lookup problem.

There is another problem with the class Object[] too...
