Sort of.

Yes, but the point is that JMeter replaces the references before
passing the script to Groovy.
So Groovy never sees the reference, and therefore cannot do its own
processing of them, which is different.
That is not a bug in JMeter.
If you wish to disable JMeter variable interpretation, prefix the
reference with backslash [1]
For example:
def v2 = "123 \${v1}"

Yes, best to use a file.
