@Jonathan Leitschuh - I'm also waiting, but worked around it by forcibly hacking (sorry) the GET_SUPPRESSED_METHOD field to null. This will give a reflection warning on JRE11, and needs to be done once at the start of your application (or, if you have multiple classloaders, on each one, though this is not something I tried, because I have not needed to):

            Field field = ThrowableProxy.class.getDeclaredField("GET_SUPPRESSED_METHOD");
            field.setAccessible(true);
            Field modifiers = Field.class.getDeclaredField("modifiers");
            modifiers.setAccessible(true);
            modifiers.setInt(field, field.getModifiers() & ~Modifier.FINAL);
            field.set(null, null);

Hope this helps.
