Subject [jira] [Commented] (SUREFIRE-1588) Surefire manifest jar classloading broken on latest Debian/Ubuntu Java8

   We should see the Manifest. Why this issue does not exist on Windows? I think it should
because the code base is in TEMP since the `surefire.jar` (surefire booter) is always on `C:\`
and not your Local repo on `D:\`.
   See the first two sentenses in https://docs.oracle.com/javase/8/docs/technotes/guides/jar/jar.html#classpath
   Are we sure that we identified the bug and it is in Class-Path of the Manifest??
   Why the Main-Class is not found according to the bugs related to Debian dist?
   The users say the `useSystemClassLoader` helps but it is because environment variable `CLASSPATH`
is used with absolute paths. It is a bit contradictory with Manifest's Class-Path. I remember
that the spec was different and that the file URL (`file:/path/to/jar`) was supported, so
I guess absolute.

>             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.
