I see this warning message. An illegal reflective access operation has occurred
You can ignore those warnings.
Ok that is good to know, can I ask what it is causing it? It looks a bit like google prying?
I am not using google for geocoding, the default is openstreetmap, so just wondering?
I should also ask how to stop it is it install default-jre and point to that?
Adrian
We use Google Guice (injection library) in some places in the code. It has nothing to do with mapping.
Is that a difference between the 32 bit and 64 bit installs, just wondering why I do not see the error on the 32 bit machine only on the 64.
Adrian
There is no 32-bit installer.
On the manual install where one has to unzip the files and place them in to a directory on the computer.
Manual doesn't come with Java VM, which means it uses VM available on your system and it likely doesn't report those warnings. Probably because older Java versions don't report them.
OK, as normal just trying to understand a bit more on the where and why things happen.
I often think I have made an error.
Thank you

Hello @Anton, I have also see that warning after I install mod_security, mod_evasive and mod_qos. I also see that in logs:

I had a chance to get hold of a 64 bit machine today so installed the 64 bit version 4.2 Linux install on a ubuntu 18.04 server operating system. I do not get this in the 32 bit computer running traccar. on ubuntu 16.04
The only differences I can think of is the version of java between the two, this 64 bit will ahve the version as installed with the install package and on the 32 bit machine I install from ubuntu.
Have added the mysql database, apache2 and made it https: all from following the installation guide, no devices yetone thing I noticed is the above warning message when I run:
sudo systemctl status traccar I get:-
I have run update and upgrade to make sure all is the latest patches. can anyone assist?
The server is working although I have not tried attaching any devices yet.
If one needs anymore information I will try to get it.
