lombok causes an IllegalArgumentException in ReferenceEquality

[Ferada]

I tracked down this crash to a single Wither annotation from Lombok. Haven't checked the GitHub master branch nor any other versions though.

Minimal example is at https://github.com/Ferada/errorprone-test with mvn clean install.

Stacktrace:

/home/olof/workspace/errorprone-test/src/main/java/com/example/Setting.java:10: error: An unhandled exception was thrown by the Error Prone static analysis plugin.

     Please report this at https://github.com/google/error-prone/issues/new and include the following:

The crash indicates that the suggest fix logic is seeing an AST node without an end position.

[Raniz85]

I'm getting this with Lombok 1.16.20 and Error Prone 2.2.0

[mkadan]

Still doesn't work with @Wither.

ErrorProne 2.3.1
Lombok 1.16.20

    @Value
    public static class Payment {

        Long id;
        // for tests
        @Wither
        String name;
    }

leads to:

error: An unhandled exception was thrown by the Error Prone static analysis plugin.

Still getting this with Lombok 1.18.6 and Error Prone 2.3.3

[msridhar]

Maybe a fix similar to #1135 inside this code will do the trick here

[yasserg]

It seems like a fix has been proposed here: #1195

package t;

import lombok.Value;

@Value
public class I447 {

  Long x;

Please re-open this or file a new bug if you're still seeing issues with Lombok and Error Prone 2.13.0 when -XepDisableWarningsInGeneratedCode is enabled.
