orig synopsis: "Labels must be identifiers"

java version "1.3.0" (and 1.4 beta43 -- see below)
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.0-C)
Java HotSpot(TM) Client VM (build 1.3.0-C, mixed mode)

JDK 1.1 correctly rejected this code, but JDK 1.3 compiles it. According to the
JLS (14.7), labels must be identifiers, and parenthesis don't fit the bill.

class foo {
  void bar() {
    int i;
    (a): i = 1;
  }
}

I verified the problem, as follows:

frog$ cat -n foo.java
     1
     2 class foo {
     3 void bar() {
     4 int i;
     5 (a): i = 1;
     6 }
     7 }
frog$ javac1.3 foo.java
frog$
