The following example fails to build with gradle and Error Prone. The issue is a VerifyError that appears to be caused by Lombok's ShadowClassLoader declaring a second copy of javax/tools/JavaFileObject$Kind.

original report: google/error-prone#589

src/main/java/Domain.java

import java.util.Date;
import lombok.Getter;
import lombok.Setter;

@Getter
@Setter
public class Domain {

  private static final long serialVersionUID = 1L;
  private Long id;
  private Long userId;
  private String imageUrlProfile;
  private Boolean defaultImage;
  private Date createdDate;

  public String getImageUrlProfile() {
    return "";
  }
}

build.gradle

buildscript {
  repositories {
    maven {
      url "https://plugins.gradle.org/m2/"
    }
  }
  dependencies {
    classpath 'net.ltgt.gradle:gradle-errorprone-plugin:0.0.8'
  }
}

apply plugin: 'java'
apply plugin: 'net.ltgt.errorprone'

repositories {
  mavenCentral()
}
dependencies {
  compileOnly 'org.projectlombok:lombok:1.16.16'
}
configurations.errorprone {
  resolutionStrategy.force 'com.google.errorprone:error_prone_core:2.0.19'
}

I tested with gradle 3.4.1 and JDK 8u151:

$ gradle build
