An exception occurred processing the request: java.net.URISyntaxException: Relative path in absolute URI

Question

Just checked the WildFly log of a system that I developed and found the following error on it:

2017-05-03 08:48:08,575 ERROR [io.undertow.request] (default task-4) UT005001: An exception occurred processing the request: java.net.URISyntaxException: Relative path in absolute URI: https://www.google.com:443http://www.google.com/

Besides https://www.google.com:443http://www.google.com/ there is also https://testp3.pospr.waw.pl:443http://testp3.pospr.waw.pl/testproxy.php and https://www.baidu.com:443http://www.baidu.com/cache/global/img/gs.gif.

Someone knows what could be the problem?

Edit: A few hours after this log there was a java.lang.OutOfMemoryError: Java heap space and the system crashed, making it needed to restart WildFly to get the system up again. I can't say for sure if the crash is related with this error.

All the classes on this log are originated from Java. In the log file, what comes after this is exactly the same, but changing from google.com to, for example, baidu.com. I don't know what originated this log, i.e., wich page. — Paulo Salgado

Wasn't sure if that was the whole trace or not. That's why I asked — Alex

My guess would be that someone is sending you a URL in the following form:

http://yoursite.com/https://www.google.com:443http://www.google.com/

Try sending that URL form your browser and see if you get similar error.

It goes to a error page, but on the log there's anything.

Oh well, it was worth a try... Sorry.

This error message is caused by web scanners executed on the website.
