By K6 I meant K7...short for Athlon/Duron family of processors.

Anyway, here's why each of the tests fail:

*************************************************************************
ThreadState.java:
*************************************************************************
/* Expected Output:
Success.
Success.
Success.
Success.
Success.
Success.
Success.
Success.
Success.
Success.
*/

what i got:

Success.
Success.
Success.
Success.
Success.
Success.
Success.
Success.
Success.
Success.

interesting, eh?  it turns out that my compiler (jikes 1.18) is spitting
out tons of lexical warning messages such as:

	Issued 10 lexical warnings in "ThreadState.java":
	
	    46.         assert(false, "main " + e);
	                ^----^
 	*** Lexical Warning: The use of "assert" as an identifier is
        deprecated, as it is now a keyword. Use -source 1.4 if you
        intended to make use of assertions.

these warnings are confusing the testing script.  when i run jikes with
the -nowarn option, this test is successful, as are:

	finaltest.java
	SortTest.java
	MapTest.java
	LineNumberReaderTest.java

the regression scripts should definitely be ignoring the compiler output
when checking to see if a test succeeds.


*************************************************************************
KaffeInternal.java:
*************************************************************************
/* Expected Output:
java.lang.NoClassDefFoundError: kaffe/lang/ThreadStack
*/

what i got:

java.lang.SecurityException: Prohibited package: kaffe/lang/ThreadStack

I believe that what I got is the expected behavior, only that between the
writing of the regression test and now the exception thrown for a class
attempting to access something that it should not be accessing has
changed.  perhaps the expected output of the regression test should be
updated?


*************************************************************************
DoublePrint.java:
*************************************************************************

what i actually got (there are some discrepencies here):

I'm not a hardware person and don't know much about floats, so i have no
idea where to begin tracking down the problem with that one...

haven't spent too much time with this one yet...


if i can post any further info about any of these tests, lemme know.
