JRE fatal error after shrinking with Proguard

I'm bundling the JRE with my JavaFX application on Mac using gradle-macappbundle. I'm trying to reduce the size of the JRE so I don't have to include the full ~200 MB. I have followed the instructions in the Java8 README to remove some optional components.

After the macappbundle plugin creates the .app, I want to run Proguard on the JRE(I'm using the gradle plugin for it) to remove even more unused classes.

My current proguard rules:

task shrinkJRE(type: ProGuardTask, dependsOn: 'createApp') {

    injars "build/macApp/"

    outjars "build/libs/pro/"



    keep "class java.** { *; }"



    ignorewarnings()

    dontobfuscate()

    dontoptimize()

}

This produces a JRE about 45 MB.

But after doing chmod +x on the JavaAppLauncher executable and running it, it shows this error:

#

# A fatal error has been detected by the Java Runtime Environment:

#

#  SIGSEGV (0xb) at pc=0x000000010c6025e4, pid=86901, tid=0x0000000000002303

#

# JRE version:  (8.0_181-b13) (build )

# Java VM: Java HotSpot(TM) 64-Bit Server VM (25.181-b13 mixed mode bsd-amd64 compressed oops)

# Problematic frame:

#

# Core dump written. Default location: /cores/core or core.86901

#

# An error report file with more information is saved as:

#

# If you would like to submit a bug report, please visit:

#   http://bugreport.java.com/bugreport/crash.jsp

#

Abort trap: 6 (core dumped)

Could anyone help me find the cause of this error?

My guess is that I'm missing some required classes for the JRE, so what are some classes I might also need to "keep"?

First of all, the license disallows to remove or change anything in JRE except Optional Files. Furthermore, JRE requires much more than just java.* classes, e.g. sun.*, com.sun.*, jdk.* etc.

As apangin said, you are not allowed to redistribute such a modified JRE. If it is only for your own environment, you’re wasting your time. The JVM loads most of the classes from the optimized archive classes.jsa (rt.jar could be replaced with an empty file), unless the jar files have a newer timestamp. See Class Data Sharing. Compare also with the documentation for newer versions which is more exhaustive about controlling the contained classes
