This error is fixed in the development version of abcl, on Jan 12.  It might not yet have arrived in any released version.

The patch (taken from source control version history) looks like this:

--- a/src/org/armedbear/lisp/Stream.java

Unfortunately, this is in the Java part of abcl and cannot be patched in an init file.  You will have to recompile the whole of abcl yourself.
