kaffe javac question: forward reference supported?

[Yong Chen]

Hi,

thank you very much for the reply, it did help me to some extent. But
unfortunately I'm still facing a problem which is related to my previous
question. I tried to compile 2 classes (each references the other) at same
time (like: kjc A.java B.java) but got exception (see below). This happens
when these 2 classes are in same package, also happens when these 2 classes
are in different packages.

Any help is appreciated.

Current version (1.4F and 1.4F-egp*) of KJC (KOPI Java Compiler) does
not support this feature.  As a workaround, you must compile classes A
and B in the same run as in

    kjc A.java B.java
