Eric Milles updated GROOVY-11011:
---------------------------------
Description:
Consider the following:
{code:groovy}
@groovy.transform.CompileStatic
class FileTreeBuilder {
def methodMissing(String name, Object args) {
if (args instanceof Object[] && args.length == 1) {
def arg = args[0]
if (arg instanceof Closure) {
dir(name, arg)
} else if (arg instanceof CharSequence) {
file(name, arg.toString())
} else if (arg instanceof byte[]) {
file(name, arg)
} else if (arg instanceof File) {
file(name, arg)
}
}
}
}
{code}
STC gives no errors for this, but there are 2 class format issues.
"args.length" is reporting bad type on operand stack and "if (arg instanceof
CharSequence)" and subsequent guards are reporting improper class name
"Ljava/lang/Object;" on the operand stack.
