Consider code like this:
---
package t;

class Test {

    void t() {
        if (true) {
            s().
        } else {
        }
    }

    String s() {
        return null;
    }
}
---

Compiling this with the current javac yields:
---
$ javac /tmp/Test.java
/tmp/Test.java:7: error: <identifier> expected
            s().
                ^
/tmp/Test.java:7: error: not a statement
            s().
               ^
/tmp/Test.java:8: error: ';' expected
        } else {
         ^
/tmp/Test.java:8: error: 'else' without 'if'
        } else {
          ^
/tmp/Test.java:12: error: ';' expected
    String s() {
            ^
/tmp/Test.java:15: error: reached end of file while parsing
}
 ^
6 errors

This seems like too much errors for a fairly small mistake. The AST structure is also not very nice.
