Thorsten,
FWIW, the primary change in the new implementation of arg files that
appeared in JDK 9 is that embedded quotes are supported. Previously, if
characters within a string needed to be escaped, the entire string had
to be escaped. Now, you can escape just part of a string. In general,
all "old-style" files should be accepted as before, but now you have
more flexibility over how you quote a string to escape parts of it.

I've filed JDK-8216522 [1] to track this general issue.
For JDK 9 onward, the syntax rules in this area come down to:
* outside of quotes, the backslash character has no special meaning
and is treated literally
* inside quotes, the backslash character is an escape character, and
must be doubled to pass through a backslash character.
As an example, the following are equivalent
C:\Users\me\myfile.java
"C:\\Users\\me\\myfile.java"
Likewise the following are equivalent
C:\Program" "Files\myfile.java
"C:\\Program Files\\myfile.java"
So, in terms of specifying paths, you only need to be careful if tyhe
path contains whitespace characters.

Guten Tag Jonathan Gibbons,

The change that you noted in the URIs is just a side-effect of internal
changes in the way that the documentation was generated. We removed the
documentation for the old implementation from 9, and it is a bug that we
did not get to update it with a reference to the new syntax, as
described for the Java launcher in [1].
Do you take care of creating a bug adding such a reference? [1] make
some points a lot more clear and is actually what I hoped to find. So
thanks for that.
Please also note that the handling of command-line arguments is
different from the handling of the contents of argument files.[...]
My link is explicitly mentioning argument files:
Examples
Single Argument File[...]
Two Argument Files
https://docs.oracle.com/en/java/javase/11/javadoc/javadoc-command.html#GUID-EFE927BC-DB00-4876-808C-ED23E1AAEF7D
And the example for Windows contains the following:
-overview \java\jdk9\docs\api\overview-summary.html
-sourcepath \java\
Which uses unescaped backslashs and should be a bug as per your linked
[1]. Am I wrong or do you take care of that as well or should I add
some bug somewhere or ...?
Mit freundlichen Grüßen,
Thorsten Schöning
