Summary: Can not call a java parameterized type method from groovy
with java enum. Compile error
Key: GROOVY-8960
URL: https://issues.apache.org/jira/browse/GROOVY-8960
Project: Groovy
Issue Type: Bug
Components: GroovyScriptEngine
Affects Versions: 2.5.5
Reporter: Stuart Adamson
Java:
{code:java}
import java.io.Serializable;
public class aJavaClass {
private aJavaClass(final A inA) {
System.out.println("Hello");
}
public static aJavaClass create(final A inA) {
return new aJavaClass<>(inA);
}
public enum aEnum {
entry1,
}
}{code}
Groovy calling class:
{code:java}
import groovy.transform.CompileStatic
import aJavaClass
@CompileStatic
class aCallingGroovyClass {
static void main(String[] args) {
aJavaClass.create(aJavaClass.aEnum.entry1)
}
}{code}
try compiling get:
{code:java}
Error:(10, 9) Groovyc: [Static type checking] - Cannot call aJavaClass#create(A) with arguments
[aJavaClass$aEnum]{code}
Replace the method arg aJavaClass.aEnum.entry1 with non enum, say '1' no
quotes, code compiles and runs.

Description:
I don't have the exact code that created this error, but the fix seems pretty
simple.
{code:java}
// excerpt from StaticVerifier.visitConstructorOrMethod
public void visitVariableExpression(VariableExpression
ve) {
if (exceptions.contains(ve.getName())) return;
/* GRECLIPSE edit --
VariableExpression.isInStaticContext is null safe
Variable av = ve.getAccessedVariable();
if (av instanceof DynamicVariable ||
!av.isInStaticContext()) { // this is line 96
*/
if (ve.getAccessedVariable() instanceof
DynamicVariable || !ve.isInStaticContext()) {
// GRECLIPSE end
addVariableError(ve);
}
}
