Did anyone notice a problem with Timbre when using JDK 17? I got a log with this stacktrace:

It looks like it's trying to access sun.security.provider.certpath.SunCertPathBuilderException which is no longer exposed in JDK 17 (or maybe some earlier JDK versions)?

rolt12:09:22

--add-exports=java.base/sun.security.provider.certpath=ALL-UNNAMED something along those lines in jvm opts ? (or add-opens even) (i don't think it's timbre related, it looks like it's aviso pretty not being able to "datafy" the exception)

jumar17:09:08

But it's timbre using aviso, right? I'm wondering what information they are trying to get that makes it more useful than plain stacktrace..

rolt21:09:42

yes, maybe you can propose a fallback when the exception is not introspectable

clj꞉user꞉> 
(StackTraceElement->vec (.getStackTrace (Thread/currentThread)))

; Execution error (ClassCastException) at user/eval9690 (REPL:138).
; class [Ljava.lang.StackTraceElement; cannot be cast to class java.lang.StackTraceElement ([Ljava.lang.StackTraceElement; and java.lang.StackTraceElement are in module java.base of loader 'bootstrap')
What is the difference between Ljava.lang.x and java.lang.x and can one be converted to the other?

p-himik17:09:22

It's [Ljava.lang.x; actually - the [ and ; bits are still important. https://stackoverflow.com/a/5085907/564509

p-himik17:09:14

And on how to convert - just map over all of them, assuming you need all of them: 

(map StackTraceElement->vec (.getStackTrace (Thread/currentThread)))

skylize17:09:24

🙏:skin-tone-3: Makes obvious sense, once you know what it means. Of course a list of stack traces is not the same as a single stack trace.

skylize17:09:56

...err I guess I mean "stack trace elements". Ok got it now. 💡
