------------------------------------
Summary: 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
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.
(Patterned after original use case involving Spring HATEOAS
ControllerLinkBuilder#methodOn.)
{code:title=VarArgsGenericsCase.groovy|borderStyle=solid}
import groovy.transform.CompileStatic
@CompileStatic
class VarArgsGenericsCase {
def markus(String name) {
methodOn(VarArgsGenericsCase.class).markus(name)
}
static <T> T methodOn(Class<T> clazz, Object... parameters) {
return clazz.newInstance()
}
}
{code}
{code}
org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
VarArgsGenericsCase.groovy: 7: [Static type checking] - Cannot find matching met
hod java.lang.Object#markus(java.lang.String). Please check if the declared type
is right and if the method exists.
@ line 7, column 9.
