A DESCRIPTION OF THE PROBLEM :
char char1 = '\u000'; is an illegal statement and it produces four compiler errors when compiles.
It is illegal because missing one hexadecimal literal in the unicode notation. So far OK.


But if try to comment out the above statement as any of the following ways;
(1)
// char char1 = '\u000';

(2)
/*
* char char1 = '\u000';
*/
(3)

/**
* char char1 = '\u000';
*/

All of them produces compiler error.
Why can't I comment out the statement as above without any problem?





STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. javac Test1.java
2. java Test1

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
While compiling Test1.java with comment statements (1) or (2) or (3) shouldn't produce any comiler error.

ACTUAL -
(1)
// char char1 = '\u000';

ON COMPILING Test1.java PRODUCES;

C:\Documents and Settings\Owner\Desktop\j2se bugs\bug1>javac Test1.java
Test1.java:10: illegal unicode escape
        // char char1 = '\u000';
                              ^

                              ^
1 error
