URL: https://github.com/apache/maven-surefire/pull/197#issuecomment-435371608
 
 
   > Why this issue does not exist on Windows?
   
   The issue is caused by a bad backport of some new security features from 
OpenJDK via JDK 10 to JDK 8 in Debian, by the Ubuntu-employed maintainer and 
the Debian security team.
   
   There are a couple new checks for JAR files, and one of them triggers the 
issue. According to someone who analysed the OpenJDK upstream changes, the 
OpenJDK team later disabled that new check by default, but this did not get 
backported to Debian.
   
   So I expect that OpenJDK itself will enable the new check some time in the 
future, at which point it will fail everywhere. For now, it only fails on 
Debian and derivatives, and it’s extremely unlucky that this change was 
forcefully pushed even onto stable release users prematurely, under the 
umbrella of security fixes and “a deliberate upstream change”.

>             Project: Maven Surefire
>          Issue Type: Bug
>    Affects Versions: 2.22.1
>            Reporter: Cservenak, Tamas
>            Priority: Major
>
> See issue [1], but in short: latest Java8 on Ubuntu/Debian/Mint family of 
> Linuxes (am on Mint, Ubuntu derivative) contains this patch [3], and eforces 
> Manifest class path entries to be relative, as defined in [2].
> Hence, surefire booter and rest of Maven classpath, that uses absolute URLs 
> are simply discarded.
> Example error:
> {noformat}
> # Created at 2018-10-30T21:34:43.339
> Error: Could not find or load main class 
> org.apache.maven.surefire.booter.ForkedBooter{noformat}
> using the new property 
> {{-Djdk.net.URLClassPath.disableClassPathURLCheck=debug}} clearly shows that 
> all the entries from the surefire JAR are simply ignored.
