["John Wagenleitner (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/GROOVY-7628?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15072087#comment-15072087 ] 

John Wagenleitner commented on GROOVY-7628:
-------------------------------------------

Think the problem is that the [ProxyGeneratorAdapter uses the classloader of the proxy|https://github.com/apache/groovy/blob/ebf4a9227697f0cfd83eb605741bcccf6605329e/src/main/org/codehaus/groovy/runtime/ProxyGeneratorAdapter.java#L148] and javafx is loaded by the Extension classloader that doesn't know of the GroovyObject (which the proxy class extends).
