Hi there, is there a way to make sure in Groovy (a) that instead of "Cannot cast object 'null' with class 'null' to class 'XXX'" for numeric primitive types XXX (like int) one gets simply a XXX containing 0 (b) that instead of "Cannot resolve which method to invoke for [null] due to overlappin

parser problem?

Hi there, lately, I have upgraded to Groovy 3.0.3 from 2.4.17, and have found expressions like this one: 1>2?[3] as Set:null which used to be parsed properly by Groovy 2 do not work anymore. It can be fixed by enclosing the [3] as Set into parentheses, but of course it's a bit at the inconven

Another ASTT question: own error collector, best way?

static propertyMissing still catches inherited methods

Hi there, I happened to bump into an ancient problem, which, alas, still seems to be sported by even the newest Groovys: a call of an inherited static method is caught by a static propertyMissing handler, which does not seem to be the intended result. Here's the ticket: https://issues.apache.o

With indy, which JARs to classpath? (was:How to test and deploy without groovy-all?)

Should “as Object[]” resolve GStrings?

Hi there, I've just bumped into this -- is it the intended behaviour? As always I might be missing something of importance, but it seems pretty inconsistent to me; I would assume all the objects inside should be left as-are, untouched: groovy:000> a=["Hi ${'there'}"] ===> [Hi there] groovy:000>

do I miss something here, or is this a Groovy bug?

dynamically install a method/property to be visible through reflexion?

Hi there, the subject says it all. I've asked this long time ago (and got a negative answer then), but meantime there's Groovy 3. Is there now a way to do that? Most important it would be with my own class (subclass of a library class), if it helps to find a solution. Thanks, OC
