I've created a minimal showcase, using jdk17 EasyMock 5.2.0 resulting with an error similar to #373 and #515:

Caused by: java.lang.LinkageError: bad field type alias: class org.easymock.internal.ClassMockingData not visible from class com.sun.net.httpserver.HttpExchange$$$EasyMock$1

on mocking com.sun.net.httpserver.HttpExchange

    @Test()
    public void test() {
        EasyMock.mock(com.sun.net.httpserver.HttpExchange.class);
    }
