Non-Sealed abstract classes not parsed

[StefanPuia]

Non-sealed abstract classes seem to not be handled properly.
I found a few threads on this since they were a preview feature, but not much since they were released.

This seems to fail with different errors depending on the order of the abstract and non-sealed tokens
abstract non-sealed:
com.google.googlejavaformat.java.FormatterException: 3:2: error: expected token: 'non'; generated class instead

non-sealed abstract:
com.google.googlejavaformat.java.FormatterException: 3:9: error: class, interface, enum, or record expected

here is an example project and the full stack trace provided by spotless

Thanks, I agree this is a bug:

package com.demo;

public abstract non-sealed class AbstractNonSealedClass extends SealedClass {

}
