1 year ago Attempting to reduce to smaller test case shows some additional interesting incorrect behavior:
import java.util.List;
@interface NotBlank {
String message();
}
record Record1(
List<@NotBlank(message = "Not blank Record1 string") String> strings,
@NotBlank(message = "Not blank Record1 str") String str) {
}
public class X {
List<@NotBlank(message = "Not blank Record1 string") String> strings;
public static void main(String[] args) {
foo( new Record1(List.of(""), "Blah"));
}
static void foo(Record1 r) {}
}This code compiled with eclipse master while javac correctly rejects it with:
X.java:8: error: annotation @NotBlank not applicable in this type context
List<@NotBlank(message = "Not blank Record1 string") String> strings,
^
X.java:13: error: annotation @NotBlank not applicable in this type context
List<@NotBlank(message = "Not blank Record1 string") String> strings;
^

The following code compiles successfully using the eclipse compiler and throws a
java.lang.annotation.AnnotationFormatError: Duplicate annotation...exception on runtime. The same code compiled with a different compiler has no issues. This leads me to believe that this is an issue with the eclipse implementation of the java compiler. Using a decompiler on the '.class' file shows that really the@NotBlankannotation has been repeated inside the type parameter of theListpost compilation.The problem occurs when calling the patch endpoint in the controller above. The exception occurs during validation of the dto.
