Paul King updated GROOVY-4744:
------------------------------
Description:
Issue GROOVY-2837 reported a problem where Groovy compiler failed if you tried
to extend a Java class with:
{code}public final Object getProperty(String s){code}
It looks like that has been fixed but the following case still fails:
{code}public final String getProperty(String s){code}
Unfortunately the Java class is within a third-party library so I can't change
it.
h4. Code to Reproduce the problem
{code}
$ head *.java
==> Java1.java <==
public class Java1 {
public final Object getProperty(String s) { return null; }
}
==> Java2.java <==
public class Java2 {
public final String getProperty(String s) { return null; }
}
{code}
{code}
$ head *.groovy
==> Groovy1.groovy <==
