It doesn't make much sense to me why we would call the super constructor with a package private data member that isn't even initialized in java/lang/ref/Reference.java except in this same constructor. There is also the problem mentioned above of queue being in another package. I think Jochen Hoenicke should look at this. The queue meant here is WeakHashMap.queue, not Reference.queue. Okay, that is a name conflict, but since Reference.queue is private it shouldn't be visible in java.util. jikes and javac don't have problems with this. I may change this, but IMHO this is also a bug in kjc. BTW the conflicts in AbstractList are serious, jikes doesn't compile subList() correctly. Jochen

And now to let you know that after trying an update on the msggen directory and not getting anything I sent this and now if I do an update on kjc-suite I get about twice as many files as the first time I did a checkout. Weird, but anyway the msggen problem is gone. Apparently I now need a com.ibm.math package for kjc-suite/xtype/. Going to go try finding this. Sorry for any confusion.

Essentially what has to be done is to use lib/makefile.dep (generated via jikes and perl) and some combination of classes.dep and java.dep to create the appropriate Makefile syntax. I've been waiting to do this for a while since jikes 1.11 should have the needed code but has not been released. I believe that Jikes 1.06 which you have will not work because it segfaults as you notice. Jikes 1.09 and 1.10 should not segfault in the way we use it.
