Adrien Guichard commented on GROOVY-11359:
------------------------------------------
FYI, After applying other modifications:
{noformat}
ClassNode retClassNode0 = ClassHelper.make(GetMethodReturn)
ClassNode retClassNode3 = new GenericsType(ClassHelper.make(GetMethodReturn,
false), [ClassHelper.make(methodNode.returnType.typeClass)] as ClassNode[],
null).type
ClassNode retClassNodeNoGenerics =
ClassHelper.make(ClassHelper.make(GetMethodReturn, false).typeClass, false)
ReturnStatement code = new ReturnStatement(
new CastExpression(retClassNode0,
new ConstructorCallExpression(
retClassNodeNoGenerics,
new ArgumentListExpression([
new StaticMethodCallExpression(
classNode,
"getMethod",
new ArgumentListExpression(
[new
ConstantExpression(methodNode.name)] as List<Expression>
)),
new MethodCallExpression(
new VariableExpression('this'),
methodNode.name,
[] as ArgumentListExpression),
] as List<Expression>)
)
)
)
// cast something
new MethodNode(
methodName,
MethodNode.ACC_PUBLIC,
retClassNode0,
[] as Parameter[],
[] as ClassNode[],
code
)
{noformat}
I do obtain the following message:
{noformat}
A transform used a generics containing ClassNode ast.type.GetMethodReturn <T
extends java.lang.Object> for the method public ast.type.GetMethodReturn
getTruc_() { ... } directly. You are not supposed to do this. Please create a
new ClassNode referring to the old ClassNode and use the new ClassNode instead
of the old one. Otherwise the compiler will create wrong descriptors and a
potential NullPointerException in TypeResolver in the OpenJDK. If this is not
your own doing, please report this bug to the writer of the transform.
{noformat}
I do not know if it is a progress.
