Jagadeesh Jayavelu updated ROASTER-116:
---------------------------------------
    Description: 
a) Roaster is not correctly reading the interfaces that extends generic type

//Interface definition
public interface AccountRespository extends CrudRepository<Account, int>
{
}

//Parsing code
JavaInterfaceSource javaInterface = Roaster.parse(JavaInterfaceSource.class, new File(file));
javaInterface.getInterfaces();

getInterfaces method is returning empty.

b) Exception when generating java code with interfaces that extends generic type

JavaInterfaceSource cu =Roaster.parse(JavaInterfaceSource.class, "public interface SomeInterface {}");
cu.addInterface("com.test.CrudRepository<Account, int>")

This throws exception
Exception in thread "main" java.lang.IndexOutOfBoundsException: Index: 0, Size: 0
	at java.util.ArrayList.rangeCheck(Unknown Source)
