A DESCRIPTION OF THE PROBLEM :
Compiler does not compile the following code:

class Rare {
    public static void main( String... args ) {
genericMethod( 5 );
}

    static <T extends Integer> void genericMethod( T i ) {
     System.out.println( i.getClass().getName() );
    }
}

The output error message is:

Rare.java:3: cannot find symbol
symbol : method valueOf(int)
location: bound of type variable T
                genericMethod( 5 );
                               ^
Fatal Error: Unable to find method valueOf

The problem seems that the compiler can not do boxing, and show a FatalError making reference to the valueOf method of the Integer wrapper class.

This bug is present with all primitive wrappers: Byte, Short, Integer, Long, Float, Double, Boolean.

The following variations compiles fine

class NotRare {
    public static void main( String... args ) {
genericMethod( 5 );
}

    static <T extends Number> void genericMethod( T i ) {
     System.out.println( i.getClass().getName() );
    }
}
Output: java.lang.Integer
( Boxing to Integer works fine )

class NotRare {
    public static void main( String... args ) {
genericMethod( 5 );
}

    static <T extends Integer> void genericMethod( T... i ) {
     System.out.println( i.getClass().getName() );
    }
}
Output: [Ljava.lang.Integer;
(Boxing to Array of Integer)


class NotRare {
    public static void main( String... args ) {
genericMethod( new Integer(5) );
}

    static <T extends Integer> void genericMethod( T i ) {
     System.out.println( i.getClass().getName() );
    }
}
Output: java.lang.Integer
(Explicit Integer argument)

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Compiles fine and show the following Output

java.lang.Integer

ERROR MESSAGES/STACK TRACES THAT OCCUR :

REPRODUCIBILITY :
This bug can be reproduced always.
