How about testing of other jpackage command line options in two phase mode? Like "--name", "--version"? Any plans to
add them?

src/jdk.incubator.jpackage/linux/classes/jdk/incubator/jpackage/internal/DesktopIntegration.java line 549:

What is the logic behind static variable?

I'd suggest to have the following initialization of "name" field:
`this.name = (name == null ? cmd.name() : name)`
This will help to avoid multiple `(name == null ? cmd.name() : name)` in the code.

Please replace main() function with dedicated test function. You can use SimplePackageTest as a template, This would
give better control on how to run the test in debug mode.

Looks like a duplicate of verify logic added with the preceding addInstallVerifier() call.

There is no need in explicit call to AdditionalLauncher.verify() as this function is scheduled for the call from
AdditionalLauncher.applyTo() call.  Thus there is no need to change access to this function from "private" to "public"
in your patch to AdditionalLauncher.java.

Please use TKit.createTempDirectory() to create directories for intermediate data of test runs. This allows clean
multiple runs of the test in the same work directory.

I don't understand what is going on here and why branching is required. Also seems like verifyPackageUninstalled()
function is never called.

test/jdk/tools/jpackage/helpers/jdk/jpackage/test/PackageTest.java line 559:

I'd rather add a loop calling DesktopIntegrationVerifier() for all launchers than copy/paste the code in
AdditionalLauncher.java
