Linux Build ISSUES:
java -version
java version "9-internal"
Java(TM) SE Runtime Environment (fastdebug build 9-internal+0-2015-10-12-105931.cbensen.jdk9udev)
Java HotSpot(TM) Server VM (fastdebug build 9-internal+0-2015-10-12-105931.cbensen.jdk9udev, mixed mode)

Test Cases
1. Simple Normal Jar (Non Modular Jar) + RPM Combination

 javapackager -deploy -verbose -outdir outdir -outfile test -native rpm -srcdir jars -srcfiles com.greetings_non_modular.jar -BmainJar=com.greetings_non_modular.jar -Bclasspath=com.greetings_non_modular.jar -appclass com.greetings.App1 -name SimpleTest
Running [rpmbuild, --version]
At least one type of shortcut is required. Enabling menu shortcut.
"Adding modules: [] to runtime image."
Exception: jdk.tools.jlink.plugin.PluginException: java.lang.Exception: Empty module paths
Config files are saved to /tmp/fxbundler7327651566835078228/linux. Use them to customize package.
Exception in thread "main" com.sun.javafx.tools.packager.PackagerException: Error: Bundler "RPM Bundle" (rpm) failed to produce a bundle.

        at com.sun.javafx.tools.packager.Main.main(jdk.packager/Main.java:484)

2. Modular Jar + Image Execution
javapackager -deploy -verbose --module-path mods -m com.greetings/com.greetings.App1 -outdir outdir -outfile test -native image -name SimpleTest
Creating app bundle: /home/rbgangad/Desktop/outdir/SimpleTest
"Adding modules: [com.greetings] to runtime image."

        at com.sun.javafx.tools.packager.Main.main(jdk.packager/Main.java:484)


3. Modular Jar + Image Execution + Specifying "jmods" folder explicitly
javapackager -deploy -verbose --module-path mods:jdk9/jmods -m com.greetings/com.greetings.App1 -outdir outdir -outfile test -native image -name SimpleTest
Creating app bundle: /home/rbgangad/Desktop/outdir/SimpleTest

        at com.sun.javafx.tools.packager.Main.main(jdk.packager/Main.java:484)

4. Modular Jar + RPM Execution
javapackager -deploy -verbose --module-path mods -m com.greetings/com.greetings.App1 -outdir outdir -outfile test -native rpm -name SimpleTest
Running [rpmbuild, --version]
At least one type of shortcut is required. Enabling menu shortcut.
"Adding modules: [com.greetings] to runtime image."
Exception: jdk.tools.jlink.plugin.PluginException: java.lang.module.ResolutionException: Module javafx.graphics not found, required by com.greetings

        at com.sun.javafx.tools.packager.Main.main(jdk.packager/Main.java:484)

5. Modular Jar + strip-native-commands false + IMAGE execution
javapackager -deploy -verbose --module-path mods -m com.greetings/com.greetings.App1 -outdir outdir -outfile test -native image --strip-native-commands false -name SimpleTest
Creating app bundle: /home/rbgangad/Desktop/outdir/SimpleTest
