How to pass the --enable-preview tomcat parameter with JSVC?
Hello,
When I deploy my tomcat war it produces the below error message, telling me
to pass the "--enable-preview". I can add the "--enable-preview" to
my non-jsvc dev tomcat start.sh script to resolve the problem fine.
BUT, if I launch the production tomcat using the jsvc binary (to
bind to port 443 instead of 8443), the JSVC binary doesn't seem to
pass the "--enable-preview" parameter.
If I try to add --enable-preview to the production JSVC
script environment:
"Invalid option --enable-preview
Cannot parse command line arguments"
What must I do to allow JSVC to accept and pass the "--enable-preview"
parameter?
apache-tomcat-9.0.27
jdk-13.0.1

I did try -Denable-preview=true -- BUT while that does allow "something"
to pass through jsvc parsing, it is not passed to the booting jsvm/tomcat
in any meaningful way. IE, the application fails to load with this error
still:

Did you try
-Denable-preview=true
?
[Would be the expected syntax (IMHO).]

Yes, I did. Neither of these work:
-D<name>=<value>
set a Java system property
-X<option>
set Virtual Machine specific option
-X--enable-preview
-D--enable-preview

Have you tried looking at the JSVC documentation?
