JSch native broken in 3.2.1.Final, known workaround?

[erik-wramner]

I'm using the JSch extension in a native Quarkus application. It worked fine in an older release (2.16), but with 3.2.1.Final (EDIT: and 3.2.2.Final) I get this trying to decrypt a SSH private key:

Caused by: java.lang.ClassNotFoundException: com.jcraft.jsch.jbcrypt.JBCrypt at org.graalvm.nativeimage.builder/com.oracle.svm.core.hub.ClassForNameSupport.forName(ClassForNameSupport.java:123) at org.graalvm.nativeimage.builder/com.oracle.svm.core.hub.ClassForNameSupport.forName(ClassForNameSupport.java:87) at java.base@17.0.8/java.lang.Class.forName(DynamicHub.java:1322) at java.base@17.0.8/java.lang.Class.forName(DynamicHub.java:1285) at java.base@17.0.8/java.lang.Class.forName(DynamicHub.java:1278) at com.jcraft.jsch.KeyPair.loadOpenSSHKeyv1(KeyPair.java:1185)

Searching for Class.forName in the JSch repo finds quite a lot of things, so even if I can register com.jcraft.jsch.jbcrypt.JBCrypt manually I'm worried that I will run into other similar errors in production.

Is this known? Is there a good way to go about this to avoid surprises? Ideally I'd like to register all the JSch classes for reflection just in case.

Fixed in next version of the extension.
