> A trait's instance initializer blocks run twice under joint compilation
> -----------------------------------------------------------------------
>
> Key: GROOVY-12575
> URL: https://issues.apache.org/jira/browse/GROOVY-12575
> Project: Groovy
> Issue Type: Bug
> Components: Compiler, Stub generator / Joint compiler
> Affects Versions: 4.0.33, 5.0.8, 6.0.0
> Reporter: Scott Murphy Heiberg
> Priority: Major
>
> When Groovy and Java sources are compiled together, each instance initializer
> block of a trait runs twice per instance:
> {code:groovy}
> trait T { List<String> log = []; { log << 'block' } }
> class C implements T {}
> {code}
> {code:java}
> public class J { public static void main(String[] a) { System.out.println(new
> C().getLog()); } }
> {code}
> {{groovyc -j T.groovy J.java}}, then {{java J}}, prints {{[block, block]}};
> compiled without {{-j}}, {{new C().log}} is {{[block]}}. Dynamic and
> {{@CompileStatic}} implementing classes behave alike.
> The stub generator runs a {{Verifier}} over each class.
> {{Verifier.visitClass}} clears the object initializer statements of a class
> after copying them into its constructors, so {{JavaStubGenerator}} saves them
> first and adds them back afterwards. For an interface or a trait,
> {{visitClass}} returns before that point and keeps them, so adding them back
> doubles them, and the trait transformation copies every block into the
> helper's {{$init$}} twice. Field initializers and static initializer blocks
> of traits are not affected.
