I'm having an issue with installing a custom query in my elasticsearch plugin. For my use case, I have a custom query PayloadPhraseQuery that uses many of the other existing Lucene phrase query code.
However when I run do a search using that query I get this error. From what I find and read online, this has to do with the fact that my PayloadPhraseQuery is loaded from a different class loader from PhraseWeight, so that even if they are both in the same package, the former can't access the latter.
I don't fully understand the nuances of the JVM and Java so I might be missing something as well.
java.lang.IllegalAccessError: class org.apache.lucene.search.PayloadPhraseQuery$1 cannot access its abstract superclass org.apache.lucene.search.PhraseWeight (org.apache.lucene.search.PayloadPhraseQuery$1 is in unnamed module of loader java.net.FactoryURLClassLoader @55bf35e5; org.apache.lucene.search.PhraseWeight is in unnamed module of loader 'app')

What would be the suggested thing to do here? I can get around this by duplicating the abstract superclasses I need, but that solution seems hamfisted to me.
