调研方向
The payload names no source files. Start by finding where Warbler assembles the fat jar with its nested JRuby, JRuby stdlib and gem jars, and how those jars are loaded at runtime through custom classloaders. The open question is how a module-compatible (JPMS) layout can carry nested jars, and that needs a design decision before any code. Done would be an agreed design plus a build that runs without the restricted-method and Unsafe warnings quoted in the issue.

描述
Warbler currently generates a single fat jar with nested jars for JRuby, JRuby's stdlib, and any other libraries needed. Those jars then get unpacked or loaded into custom classloaders at runtime.
This system will definitely need tweaks to support JPMS, the Java module system, and I do not know how to handle nested jars with a module-compatible package. We'll need to figure that out.
Modularizing will also get us closer to eliminating JVM warnings and errors related to native access and reflective access to JDK classes needed by JRuby proper, such as the following two warnings from JDK 25:
WARNING: A restricted method in java.lang.System has been called
WARNING: java.lang.System::load has been called by com.kenai.jffi.internal.StubLoader in an unnamed module (file:/var/folders/5n/y5_kd6x94rndnyjh4519bp2w0000gn/T/jruby9794538498169631325extract/jruby-core-10.0.2.0-complete.jar)
WARNING: Use --enable-native-access=ALL-UNNAMED to avoid a warning for callers in this module
WARNING: Restricted methods will be blocked in a future release unless native access is enabled
WARNING: A terminally deprecated method in sun.misc.Unsafe has been called
WARNING: sun.misc.Unsafe::putLong has been called by com.kenai.jffi.UnsafeMemoryIO$UnsafeMemoryIO64 (file:/var/folders/5n/y5_kd6x94rndnyjh4519bp2w0000gn/T/jruby9794538498169631325extract/jruby-core-10.0.2.0-complete.jar)
WARNING: Please consider reporting this to the maintainers of class com.kenai.jffi.UnsafeMemoryIO$UnsafeMemoryIO64
WARNING: sun.misc.Unsafe::putLong will be removed in a future release
Without modules, there's no way for us to configure the generated jar with necessary permissions.
