quarkus: Possible Lombok Incompatibility

Sorry if this is not really a Quarkus bug. I’m a newcommer to Quarkus working on a proof of concept. I have a project that is making some minimal use of Lombok annotations. When running mvn quarkus:dev, occasionally after modifying one of the Lombok-annotated classes and trying to refresh the browser, I get a an error with the below stacktrace.

Expected behavior Code recompiles successfully.

Actual behavior

    Can't initialize javac processor due to (most likely) a class loader problem: java.lang.NoClassDefFoundError: com/sun/tools/javac/processing/JavacProcessingEnvironment

To Reproduce Steps to reproduce the behavior:

1. Modify a file annotated with Lombok @Data
2. Refresh in the brower causing the code to re-compile.

Environment (please complete the following information):

• Output of uname -a or ver: This is on Windows 10 version 1903,
• Output of java -version:

openjdk version "1.8.0_212"
OpenJDK Runtime Environment (AdoptOpenJDK)(build 1.8.0_212-b04)
OpenJDK 64-Bit Server VM (AdoptOpenJDK)(build 25.212-b04, mixed mode)

• GraalVM version (if different from Java): N/A
• Quarkus version or git rev: 0.21.3

Additional context If it matters, this is a multi-module maven project with two modules web and service. web is the quarkus module. Both web and service have a few classes using Lombok.
