Paul King created GROOVY-9726:
---------------------------------
Summary: Compile error needed for illegal field modifier
combination
Key: GROOVY-9726
URL: https://issues.apache.org/jira/browse/GROOVY-9726
Project: Groovy
Issue Type: Improvement
Affects Versions: 2.5.13, 3.0.5
Reporter: Paul King
The JLS (recent versions at least) states:
{quote}
It is a compile-time error if a final variable is also declared volatile.
{quote}
Compiling this class:
{code}
public class Foo {
final volatile String foo = "bar";
}
{code}
in Java gives the following compilation error:
{noformat}
error: illegal combination of modifiers: final and volatile
{noformat}
Groovy currently passes compilation but then gives the following error at
runtime when trying to create an instance of such a class:
{noformat}
java.lang.ClassFormatError: Illegal field modifiers in class Foo: 0x52
{noformat}
Groovy should also have a compilation error for this case.
