Hmm, this seems like an orthogonal issue to me.

In other words, the problem you're describing already exists, and it's just being uncovered by this change.

For example, if you compile this class:

import java.util.NO;
while
import java.io.NO;

you get this result:

Test.java:2: error: class, interface, enum, or record expected
while
^
1 error


If you compile this class:

import java.util.NO;
(
import java.io.NO;

you get this result:

Test.java:2: error: class, interface, enum, or record expected
(
^
1 error

The fact that a syntax error inhibits resolution of imported package names is happening somewhere else downstream in the compiler.

I'm not opposed to fixing that, but it seems like it should be filed as a separate issue, because (as the above examples show) it's a more general problem than just with extra semicolons.
