Hi,
according to the JLS (p. 66) I think the following block of code should be allowed

but my IDE (Eclipse) reports this as an error. Did I make a wrong interpretation of the JLS or is the Eclipse IDE a bit too restrictive in this case ?
Thanks.

This is an error. You can not implicitly cast a short (2 bytes) to a byte (1 byte).
However, if the value you are assigning is a constant (and therefore known at compile time), the assignment is allowed, as long as the value fits into the destination type.
Try making your short final - that will make it a compile-time constant and I believe your code will work.

Thanks, after reading the JLS section again it states clearly that the expression should be constant. Making it final does indeed work.
