noClassDefFoundError jvmdowngrader

[scott-ish]

Nice project.
When trying to use the dependency 0.15.1 from Maven central I get a runtime exception regarding the jvmdowngrader. Is this needed, as its not in the dependency tree?
Seems like the EventBus class uses:
import bento-fx.xyz.wagyourtail.jvmdg.j21.stub.java_base.J_L_MatchException;

and in the switch:
switch (jvmdowngrader$switch$fire$0(event, var17)) {

Caused by: java.lang.NoClassDefFoundError: bento-fx/xyz/wagyourtail/jvmdg/j21/stub/java_base/J_L_MatchException
at bento.fx/software.coley.bentofx.Bento.newEventBus(Bento.java:39)
at bento.fx/software.coley.bentofx.Bento.(Bento.java:28)

Looks like this is not a problem in the current repo but just with centrals dependency.

Hi @Col-E,

I noticed:

• BentoFX on GitHub shows Release 0.15.1 (Latest)
• The most recent version of BentoFX that is available from Maven Central is 0.15.1
  • Maven Central uses the "old" GAV

    <dependency> 
        <groupId>software.coley</groupId>   
        <artifactId>bento-fx</artifactId>   
        <version>0.15.1</version>   
    </dependency>
    

• But Issue 30 is still open to Publish relocation stub for 0.15.2
• And gradle/libs.versions.toml in master specifies bentofx = "0.16.0" which
  • Specifies the "new" GAV

  <dependency>   
      <groupId>software.coley.bento-fx</groupId>   
      <artifactId>core</artifactId>   
      <version>${version}</version>   
  </dependency>
  

I'm curious about plans for publishing updates to Maven Central?

Much obliged for all of you work on this!

So for Java 17 backporting (previously requested and now removed) there was a post-processing layer on the artifact that downsampled the output bytecode and added any missing stub classes like bento-fx.xyz.wagyourtail.jvmdg.j21.stub.java_base.J_L_MatchException. Those should be present in the release jar, and I've not encountered any issue with their usage.

Can you pass me the full stacktrace and any caused by blocks? I'm curious why its failing for you but not for me.

The plan was to publish that once the new module for persistence was available so that there would be something to redirect to.

I'll update that issue to provide status.
