[Jscheme-devel] Weird behaviour under Java 5

[Tatu T. <tat...@ma...>]

Some Java-calls don't seem to work under JDK 1.5.0.
Using quasi-strings fails, because the StringBuffer append method fails.

This happens with the latest jscheme jar and the CVS version.
I think the reflective access to the append method fails because in Java
5 the java.lang.StringBuffer class inherits from a new
java.lang.AbstractStringBuilder class which is not public and also
provides the append method.

I'll look into a patch over the weekend.

Here is a capture of the failure:

The errors just go on and on, until the process is killed.
