JDK1.1 have changed a set of error messages that are reported
for lang/EXPR/expr777/expr77716 test case of JCK1.1.

JDK1.0.2 detects illegal static reference to nonstatic variable
in lines 15, 31, 33.

Some preJDK1.1M version detects single error in lines 15.

And finally JDK1.1M shows only error in line 31.

I like more JDK1.0.2 behaviour in this case
but if extra messages are suppressed in JDK1.1
it would be more reasonable to report error message
at the first line it occurs namely the line 15 not 31.

See compiler outputs and test source below.
