Java Utililty Methods Throwable to String

Necessary because slf4j does not by default have a method for logging exceptions

StringWriter writer = new StringWriter();
PrintWriter pwriter = new PrintWriter(writer);
writer.append(e.getClass().getCanonicalName());
if (e.getMessage() != null) {
    writer.append(": ");
    writer.append(e.getMessage());
writer.append('\n');
