-----------------------------------
Assignee: Eric Milles
> Problem with @CompileStatic, generic types, and varags
> ------------------------------------------------------
>
> Key: GROOVY-7648
> URL: https://issues.apache.org/jira/browse/GROOVY-7648
> Project: Groovy
> Issue Type: Bug
> Components: groovy-jdk
> Affects Versions: 2.4.4
> Reporter: Adam Augusta
> Assignee: Eric Milles
> Priority: Major
>
> Similar to GROOVY-7182, groovyc fails to handle generic types if a class uses
> @CompileStatic and the generically typed method has a varargs parameter.
> Removal of @CompileStatic or the varargs parameter eliminates the compile
> error.
> (Clarification: methodOn need not be defined in the @CompileStatic class. In
> the original case, the method was ControllerLinkBuilder#methodOn from
> Spring's HATEOAS library.)
> {code:title=VarArgsGenericsCase.groovy|borderStyle=solid}
> import groovy.transform.CompileStatic
> @CompileStatic
> class VarArgsGenericsCase {
> def markus(String name) {
> methodOn(VarArgsGenericsCase).markus(name)
> }
> static <T> T methodOn(Class<T> clazz, Object... parameters) {
> return clazz.newInstance()
> }
> }
> {code}
> {noformat}
> org.codehaus.groovy.control.MultipleCompilationErrorsException: startup
> failed:
> VarArgsGenericsCase.groovy: 7: [Static type checking] - Cannot find matching
> method java.lang.Object#markus(java.lang.String). Please check if the
> declared type is correct and if the method exists.
> @ line 7, column 9.
