> io.undertow.servlet.spec.ServletPrintWriter.checkError() does not flush the stream.
> according to JDK docs, printWriter.checkError()  'Flushes the stream if it's not closed and checks its error state'.   This bug discovered by accident when converting a Payara to wildfly, which used checkError to flush the stream, and check errors.
