Hello, Seems not possible to pass options beside the known ones:
https://gitbox.apache.org/repos/asf?p=commons-daemon.git;a=blob;f=src/native/unix/native/arguments.c;h=8160c72944a7d7dae9cc8d43ec244f43a664a82f;hb=HEAD#l425 One option is to pass all unknown options to java, another is to pass only the missing --enable-preview and lastly an repeatable option --add-jvm-arg "--enable-preview". I think passing the options might be most flexible, but it needs to make sure to correctly detect spaces --start --enable-preview -splash:"/Home/Insane User/foto.jpg" Maybe adding the one missing option is fastest. As a workaround, maybe you can use environment variable JDK_JAVA_OPTIONS?

Hello, How do you pass a command line parameter such as --enable-preview while using JSVC? jsvc -help shows -X and -D but neither of these are appropriate for an openjdk command line parameter like --enable-preview ?!?!?!? -D<name>=<value> set a Java system property -X<option> set Virtual Machine specific option Ken
