The runtime can process machine language sources as well as executables from different language compilers.

The Java compiler uses reflection to test if class methods are supported by resources of a target platform.

The Java compiler preprocesses classes to run on specific target platforms.

jdeps lists the module dependencies and the package names of all referenced JDK internal APIs. If any are found, the suggested replacements are output in the console.

jdeps outputs an error message that the -jdkinternals option requires either the - summary or the - verbose options to output to the console.

The -jdkinternals option analyzes all classes in the .jar and prints all class-level dependencies.
