A DESCRIPTION OF THE PROBLEM :
Compilation of the enclosed program is very sensitive to the order in which the source files are presented.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Unpack the sources and try

javac U.java

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Compiles successfully
ACTUAL -
Fails to compile

ERROR MESSAGES/STACK TRACES THAT OCCUR :
U.java:5: cannot find symbol
symbol  : method i()
location: class E
	E.V.i();
           ^
1 error


REPRODUCIBILITY :
This bug can be reproduced always.

---------- BEGIN SOURCE ----------
==> I.java <==
interface I {
 void i();
}

==> E.java <==
enum E implements I {
 V { public void i() { } };
 // public abstract void i();
}

==> U.java <==
class U {
 {
   I i = E.V;
   i.i();
   E.V.i();
 }
}
---------- END SOURCE ----------

CUSTOMER SUBMITTED WORKAROUND :
running 'javac E.java && javac U.java' succeeds.

Uncommenting line 3 of E.java also works around the problem.
