CC Mode 5.28 How to turn off auto completion certain keywords ?

[Thanh Ngan Dang]

Hi,

I've downloaded CC-Mode 5.28 package to used with Xemacs 21.1.9
for windows NT and I encountered an unwanted feature.

in java mode (or in a java file) every time I type a word
for example "by" and following by space bar, CC-mode expand 
the word "by" to "byte" and same thing for "th" to "this",
"ch" to "char" etc .... This is anoying because some time
I am writing comments and the "feature" keeps expanding
to unwanted words. I tried to read cc-mode faq at the CC-Mode
web page, read online documents and found nothing. I am not
familliar with LISP so I can't read the source code come
from with the CC-Mode 5.28. I'll appreciate if some one
can help me how to turn of this feature. Thank you.

Before installing CC-Mode 5.28, I was using cc-mode 5.25 
and the "feature" wasn't there.

Thank you
