#73 implied constant promotion aborts compilation

[Anonymous]

public class O
{
public void m() { long l = 5; }
}

Compiling this class with Janino 2.1.0 using Sun's
1.4.2_06-b03 JVM under Windows results in the
compilation being aborted with this error message:

java.lang.RuntimeException: O.m(): Operand stack
underrun at offset 1

Putting "5L" at the right-hand side of the equals sign
compiles. Looks like Janino doesn't promote the
constant "5" from its default type (int) to the needed
type (long), or something.

The assignment conversion was missing for local variable
initializers. No problem for byte/short/char/int, but if the
variable or the initialzer have type long/float/double, then
you get JVM errors.

Not good programming style to write "double x = 0", eh? ;-)

Added assignment conversion. Will be fixed in the next
(post-2.1.0) release; not scheduled yet.

Could you attach a patch here in the meantime? Thanks.
