The class 'MonthEnum' (complete code below) compiles and runs perfectly using 
jdk1.5 javac/java.

When loading it up into 3.1M1, the editor displays two errors, and fails to 
compile for the same reasons:

1) in the `switch(this)` statement (line 23), 'this' is underlined in red and 
the following error is displayed:
    "case constant must be a char, byte, short, or int instead of MonthEnum"

2) in the `println(JANUARY.getDays())` call, JANUARY is underlined in red, and 
the error displayed reads:
    "JANUARY cannot be resolved"

Compilation/running fails (Unresolved compilation error on #2 above), and I can 
go no further.

Thanks for your attention to this!
