Error when cross compiling with JDK 13, release flag and JFR package

ADDITIONAL SYSTEM INFORMATION :
System Version: macOS 10.15.3 (19D76)
Kernel Version: Darwin 19.3.0

$ java -version
java version "13.0.2" 2020-01-14
Java(TM) SE Runtime Environment (build 13.0.2+8)
Java HotSpot(TM) 64-Bit Server VM (build 13.0.2+8, mixed mode, sharing)

A DESCRIPTION OF THE PROBLEM :
For code that uses the JFR package, cross compilation (--release X) does not work when using JDK 13 or 12. It seems to be a regression since the same problem does Not exist in JDK 10 and 11.

 For below java code, assuming it's called "App.java", the command "javac --release 11 App.java" fails with two types of errors:

* annotation @Label is missing a default value for the element 'value'
* reference to commit is ambiguous

```
package jfrtest;

import jdk.jfr.Category;
import jdk.jfr.Event;
import jdk.jfr.Label;

public class App {

    @Label("Hello World")
    @Category({"Sample", "My Custom Event"})
    static class HelloWorldEvent extends Event {
        @Label("My Message")
        String msg;
    }

    public static void main(String[] args) {
        HelloWorldEvent event = new HelloWorldEvent();
        event.msg = "Hello World event message!";
        event.commit();
    }
}
```

REGRESSION : Last worked in version 11.0.6

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
For the attached source code (App.java), the following compilation command results in errors:
javac --release 11 App.java

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
It should successfully generate the class files.
ACTUAL -
It errors out with following messages:

App.java:9: error: annotation @Label is missing a default value for the element 'value'
    @Label("Hello World")
    ^
App.java:10: error: annotation @Category is missing a default value for the element 'value'
    @Category({"Sample", "My Custom Event"})
    ^
App.java:12: error: annotation @Label is missing a default value for the element 'value'
        @Label("My Message")
        ^
App.java:11: error: reference to Event is ambiguous
    static class HelloWorldEvent extends Event {
           ^
  both constructor Event() in Event and constructor Event() in Event match
App.java:19: error: reference to commit is ambiguous
        event.commit();
             ^
  both method commit() in Event and method commit() in Event match
5 errors


---------- BEGIN SOURCE ----------
package jfrtest;

import jdk.jfr.Category;
import jdk.jfr.Event;
import jdk.jfr.Label;

public class App {

    @Label("Hello World")
    @Category({"Sample", "My Custom Event"})

CUSTOMER SUBMITTED WORKAROUND :
The workaround is either:
* Do no use cross compilation, i.e. remove the '--release X` option, or
* Use version 11 and under

FREQUENCY : always
