…Closes jruby#3163 MRI checks if the EXCL flag is Qnil to see if the range has been initalized. This doesn't work in Java because we use a boolean which can't have a nil value. Instead, introduce a new isInited flag which is used to track the initialization state of the Range, which corrently permits #dup while not permitting reinitialization of a Range.

Closes #3163
MRI checks if the EXCL flag is Qnil to see if the range has been initalized. This doesn't work
in Java because we use a boolean which can't have a nil value. Instead, introduce a new isInited
flag which is used to track the initialization state of the Range, which corrently permits #dup
while not permitting reinitialization of a Range.
