the latest error I’m getting:

Error: Class initialization of org.joda.time.UTCDateTimeZone failed.
Caused by: java.lang.NullPointerException: Cannot invoke "String.hashCode()" because the return value of "org.joda.time.UTCDateTimeZone.getID()" is null

Probably some code that runs on toplevel which doesn't work good with graalvm, maybe you can delay the class initialization to runtime?

let me try that

yeah, a static class: https://github.com/JodaOrg/joda-time/blob/master/src/main/java/org/joda/time/UTCDateTimeZone.java#L26

You should really be using #clj-easy graal-build-time which will only initialize clojure code at build time

but if his lib use joda time there is no other way right?

And another thing: why use joda-time if there's java.time?

it depends if that lib is initializing classes on the top level or not

yeah, I’m trying to use clj-easy , great stuff btw 🙂

absolutely agree about java.time, but unfortunately we have some legacy code which uses joda-time

and this project is a POC for using native-image so getting rid of joda-time is not in the scope

ofc maybe that would be easier 🙂

Not sure this is helpful, but I had exactly this problem, spent a whole lot of time trying different things to resolve, and in the end, gave up and migrated to java.time.

sure, that helps 🙂 one more reason not to fight with it

thanks

you'll migrate at one point in the future anyways, so you might as well bite the bullet now :)
