Start with the minimal PopupMenuButton.java reproducer and the stack location in org.eclipse.jdt.internal.compiler.ProcessTaskManager.java:139; compare the behavior with the related issue 3956. Done means compiling the reproducer no longer produces an internal compiler error for {@link JButton#JButton()} while preserving valid Javadoc link handling.
