Annotation processors were actually carefully designed to prohibit what Lombok does. Lombok hacks into javac and manipulates the AST. Unsurprisingly, there is breakage with every Java release and with other tools that work similarly, like Google Error Prone, which gets a pass since it's read-only and the build will still work if you turn it off. Class loader and reflection shenanigans can be shut down with the module system. Garbage collection matters when you stress the JVM to its limits. Don't do that.
