Wilson Leung created GROOVY-11581: ------------------------------------- Summary: byte array casted to array list when calling parent method from nested class Key: GROOVY-11581 URL: https://issues.apache.org/jira/browse/GROOVY-11581 Project: Groovy Issue Type: Bug Affects Versions: 4.0.9 Reporter: Wilson Leung
{code:java} import groovy.transform.CompileDynamic class Foo { void test() { def byteArr = 'FOO'.bytes (new NestedFoo()).printClass(byteArr) } private static bar(def val, def apple) { println "bar class: ${val.getClass()}" // prints array list } private static baz(def val) { println "baz class: ${val.getClass()}" // prints byte array } @CompileDynamic class NestedFoo { def printClass(def val) { println "nestedFoo class: ${val.getClass()}" bar(val, '') baz(val) } } } (new Foo()).test() {code} Byte arrays are being casted to an array list when calling a parent method from a dynamically compiled nested class. In the code above the call to bar will cast the byte array to an array list. This does not happen in the call to baz. It seems like this only happens when the method called takes more than one arg. I was able to reproduce this in groovy 4.0.9, I have not tested this in earlier versions. To reproduce 1) Nested class must be compiled dynamically 2) The parent method being called must take at least two arguments. It does not get casted when the method takes a single argument. -- This message was sent by Atlassian Jira (v8.20.10#820010)
