Eric Milles updated GROOVY-10407:
---------------------------------
Fix Version/s: 2.5.21
> unchecked method invocation warning in generated stubs
> --------------------------------------------------------
>
> Key: GROOVY-10407
> URL: https://issues.apache.org/jira/browse/GROOVY-10407
> Project: Groovy
> Issue Type: Bug
> Components: Compiler
> Affects Versions: 3.0.9
> Reporter: Joseph Price
> Assignee: Eric Milles
> Priority: Minor
> Fix For: 3.0.10, 4.0.0-rc-2, 2.5.21
>

>
> When calling a groovy class from java that takes a Map in the constructor,
> the generated stubs have what looks to be a second constructor that takes a
> null for the parameter, that casted to a raw Map. Since this happens in
> generated code not under my control, this prevents enabling -Werror across
> the project. Providing type arguments for the map or leaving the cast off
> would fix the warning, but I also wonder if suppressing the constructor is
> possible.
> Below are the commands I ran, along with the contents of the java and groovy
> files:
> {code:java}
> groovyc -j -FWerror -FXlint:unchecked Test.java Base.groovy
> org.codehaus.groovy.control.MultipleCompilationErrorsException: startup
> failed:
> Compile error during compilation with javac.
