NPE with nested annotations

[bsinclair2-atlassian]

Hi, I ran into an exception with a file in my codebase which uses these nested @ annotations. If I remove the @ from @Index then there is no exception, but with it I get the null pointer exception. The javaVersion parameter doesn't change the result.

package com.example.entity;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.Index;
import javax.persistence.Table;

@Entity
@Table(name = "MY_TABLE", indexes = { @Index(name = "NAME_IDX", columnList = "name") })
public class MyTable {
    @Column(name = "name", nullable = false)
    private String name;
}

Command and stack trace

rascal> createAstFromFile(dodgyFile(), true, errorRecovery = true, sourcePath = [srcDirectory()], javaVersion = JLS13());
