Hi, Petr,

the fix looks fine (I see it's been resolved already). However, it would 
be fine to document the new behavior somewhere.

BTW, have you verified that this fix doesn't break JCK tests? I haven't 
seen anywhere in JavaDoc that getScrollMode() must return the value 
previously set with setScrollMode(), but I can imagine JCK tests 
checking that. If such tests exist, they should be corrected, but it 
doesn't eliminate the need to document the new behavior.
