Hi there,
having enclosed all the “foo as bar”'s in ternary operators in parentheses, I
have bumped into a completely weird problem which I can't wrap my head on --
for many classes I am with Groovy 3 getting completely weird errors of kind
“constructor X in class Y cannot be applied to given types”
What gives and how to solve the problem? Note again that the code _did_ build
and _did work properly_ (tested zillion times) with Groovy 2, so there can't be
anything seriously wrong with the sources. Looks like another breaking change :(
I succeeded to isolate it into a pretty small source with just one pretty
standard JAR like this:
