TlsSyslogFrame appears to be miscalculating the message length.  According to RFC5425, the message length must be the octet count of the SYSLOG-MSG in the frame.  Though the variable below is aptly named messageLengthInBytes, it is assigned the value from message.length() (where message is a String) rather than the bytes.

See below for relevant portions of code:

private String message;
private int messageLengthInBytes;

private void setLengthInBytes() {
    messageLengthInBytes = message.length();
}

@Override
public String toString() {
    final String length = Integer.toString(messageLengthInBytes);
    return length + Chars.SPACE + message;
}
