Eric Milles updated GROOVY-12000:
---------------------------------
Description:
Consider the following:
{code:groovy}
@groovy.transform.TypeChecked
void test(Number number) {
if (!(number instanceof Cloneable || number instanceof Closeable)) {
number
} else {
number
}
}
{code}
Currently this passes the check for "can invert" and produces a type like
(Number & (Cloneable | Closeable))" for the else path. Not sure if we're ready
for that or not.
