Description

I recognized some strange behaviour when using latest Lombok release with NetBeans 11.3.

When using @Builder and @Builder.Default

package it.impl.lombok.netbeans.poc;

import lombok.Builder;
import lombok.Getter;

@Getter
@Builder
public class Configuration {

  @Builder.Default
  private long config1 = 500L;
}

1) A NullPointerException occurs

2) The class seems to be unresolvable

When commenting the @Builder.Default annotation out. The problem seems to be solved.

In addition it seems that the entire package cannot be used for auto completion and/or auto import.
Compile and build via maven is working like expected.

An example maven project is attached.
