One possible modification to Heri's answer - instead of StringBuilder one can use ByteArrayOutputStream - that helps if one deals with multi-language data, e.g.

// [...]
PrintStream getPrintStream() {
    if (printStream == null) {
        OutputStream output = new OutputStream() {
            ByteArrayOutputStream baos = new ByteArrayOutputStream()

            @Override
            public void write(int b) throws IOException {
                baos.write(b)
            }

            @Override
            public void flush() {
                logger.debug(this.baos.toString())
                baos = new ByteArrayOutputStream()
            }
        }
        printStream = new PrintStream(output, true)  // true: autoflush must be set!
    }
    return printStream
}
// [...]
