----------------------------------------
Summary: Incorrect bytecode generated for default interface
methods with array parameter
Key: GROOVY-10513
URL: https://issues.apache.org/jira/browse/GROOVY-10513
Project: Groovy
Issue Type: Bug
Components: Compiler
Affects Versions: 4.0.0
Reporter: Renato Athaydes
Given the following interface:
{{interface MyTrait {}}
{{ default String loadKeyStoreFrom(String url, Object... passwordChars) {}}
{{ ''}}
{{ }}}
{{}}}
Compile this to a jar file (this matters as the bug does not happen when
compiled at the same time).
Now, run this test:
{{package tests}}
{{import org.junit.jupiter.api.Test}}
{{class ExampleTest implements MyTrait {}}
{{ @Test}}
{{ def 'my test'() {}}
{{ assert loadKeyStoreFrom('', ''.chars) == ''}}
{{ }}}
{{}}}
I get the following error:
{{▶ groovy -cp build/libs/groovy-tests-1.0-SNAPSHOT.jar
src/test/groovy/tests/ExampleTest.groovy
org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
/experiments/groovy-tests/src/test/groovy/tests/ExampleTest.groovy: -1: The
method 'java.lang.String loadKeyStoreFrom(java.lang.String,
[Ljava.lang.Object;)' has an incorrect modifier transient.
@ line -1, column -1.
1 error
}}
This used to work in Groovy 3.0.9. It also works, as mentioned, if you compile
the interface and the test at the same time.
Please notice that this error also happens when using {*}traits{*}, which is
how I came across the problem.
