Graal: issue with okhttp with graalvm-ce-19.0.0

[ludoch]

With graalvm-ce-19.0.0 I get

...
Caused by: java.nio.charset.UnsupportedCharsetException: UTF-32BE
    at java.nio.charset.Charset.forName(Charset.java:531)
    at okhttp3.internal.Util.<clinit>(Util.java:75)
    at com.oracle.svm.core.hub.ClassInitializationInfo.invokeClassInitializer(ClassInitializationInfo.java:347)
    at com.oracle.svm.core.hub.ClassInitializationInfo.initialize(ClassInitializationInfo.java:267)

Which I did not have with the RC candidates...
Is it a regression or a feature? Any workaround?

did not change in my tests between RCs and 19.0.0.

Correction: I changed the okhttp version so this is not related to the 19.0.0 release.
Anyway, the bug is valid with this version of okhttp3

[ludoch]

Solution: add this in your reflect.json configuration

  {
  "name" : "sun.nio.cs.ext.ExtendedCharsets",
    "allDeclaredConstructors" : true,
    "allPublicConstructors" : true,
    "allDeclaredMethods" : true,
    "allPublicMethods" : true,
    "allDeclaredClasses" : true,
    "allPublicClasses" : true
  }

As this class in initialized via reflection in the OpenJDK Charset class.

[ludoch]

Sorry, spoke too soon... My json file does not fix this...

[causalnet]

Try the -H:+AddAllCharsets command line option when running the native image generator.

from the help text:

-H:±AddAllCharsets Make all hosted charsets available at run time. Default: - (disabled).

[vjovanov]

We changed class initialization to delay class to runtime by default. This exposes extra JNI functions that were not there before. You can find out more here.

[ludoch]

Great, thanks for the info in the flag which works. Feel free to close the bug, I am sure it will help others even if closed.

What is the best way to add just those 2 charsets (without using -H:±AddAllCharsets)?

I have seen implementation in LocalizationFeature, but even with static initialization in my cade, when a class is put into build_time_classes*.txt, it still fails with java.nio.charset.UnsupportedCharsetException: UTF-32BE.

@szpak Did you ever figure that out?
