watch protocol - NumberFormatException

I am using watch protocol. Sometimes I see in the log that an exception is happening while it reports LBS.

Like with bellow message:
[3G*12000000022*00DD*UD,010120,025946,V,0.0,N,0.0,E,22.0,0,-1,0,100,98,0,0,00000000,0,5,eduroam,f4:db:e6:d2:a8:00,-53,eduroam,f4:db:e6:da:d0:80,-79,eduroam,78:0c:f0:24:f9:80,-82,Lions,b0:be:76:0a:05:9a,-82,tubs-guest,f4:db:e6:d2:a8:01,-53,0.0]

Directly after this message in the logs, I see:
WARN: [f3b415a4] error - For input string: "eduroam" - NumberFormatException (... < WatchProtocolDecoder:146 < *:267 < ExtendedObjectDecoder:52 < ... < WrapperContext:102 < ...)

I think traccar is facing some problem during decoding the message, but still not sure.

1. What version of Traccar are you using?
2. Do you have protocol documentation?

1. I am using Traccar version 4.15.
2. Here is the link to the protocol documentation.

1. Have you tried 5.0 or even better master?
2. Your documentation doesn't match your actual sample.

1. I will try with master and will feedback accordingly.
2. Ohh... I will ask manufacturer if they have something different.

Here I get the updated protocol documentation from the manufacturer.

And what about trying the master?

I run the test on master and it didn't passed, the same problem still exists.

A part of the test error:

For input string: "eduroam"
java.lang.NumberFormatException: For input string: "eduroam"
	at java.base/java.lang.NumberFormatException.forInputString(NumberFormatException.java:67)
	at java.base/java.lang.Integer.parseInt(Integer.java:660)
	at java.base/java.lang.Integer.parseInt(Integer.java:778)
	at org.traccar.protocol.WatchProtocolDecoder.decodePosition(WatchProtocolDecoder.java:163)....

I created a pull request #4874 which may this problem with.
