It’s a good question, but your implmenetation assumes a lot. I presume you have to document the name of your jar for your users to invoke “java -jar xyz.jar” on so can you also include in the documentation that “-Xmx256M” is required?
You may have more luck using a java launcher, such as this one for Windows, where you put the launcher config (path, max memory etc.) in a separate file. For cross platform, there’s LaunchAnywhere, and others, which function similarly. See How can I convert my Java program to an .exe file?
To improve upon your existing scheme:
java.homesystem property to resolve the location of the JDK/JREjava.class.pathto set up the class path, and similarly forjava.library.pathif your application requires native code.But still, this seems to be a lot of effort that at best represents a leaky abstraction, when instead simple and clear documentation would suffice.
