I'm guessing probably the cause listed on line 216 is more informative

Indeed:

Detected an instance of Random/SplittableRandom class in the image heap.

I recommend using https://github.com/clj-easy/graal-build-time

I understand why, but I can't solve the problem I've set the parameters in native-image: • --enable-all-security-services which will be depreciated • "--initialize-at-run-time=java.security.SecureRandom" https://github.com/moclojer/moclojer/actions/runs/6524999120/job/17717217017?pr=153#step:7:179 full backtrace

Error: Classes that should be initialized at run time got initialized during image building:
 java.security.SecureRandom the class was requested to be initialized at run time (from command line with 'java.security.SecureRandom'). com.sun.jndi.dns.DnsClient caused initialization of this class with the following trace: 
	at java.security.SecureRandom.<clinit>(SecureRandom.java:158)
	at sun.security.jca.JCAUtil$CachedSecureRandomHolder.<clinit>(JCAUtil.java:65)
	at sun.security.jca.JCAUtil.getSecureRandom(JCAUtil.java:77)
	at com.sun.jndi.dns.DnsClient.<clinit>(DnsClient.java:86)

You should still not use —initialize-at-runtime without arguments. This is deprecated. Look at the library I linked to earlier and use that one

I tried to use it, but I had to release library by library manually - it wasn't automatically reading everything I used in the project > I'll try again

so, we added this,

--allow-incomplete-classpath
--features=clj_easy.graal_build_time.InitClojureClasses
--enable-all-security-services
--initialize-at-run-time=java.security.SecureRandom
--initialize-at-run-time=org.apache.poi.util.RandomSingleton
--initialize-at-run-time=com.fasterxml.jackson.core.io.SerializedString
--initialize-at-run-time=sun.security.ssl.SSLContextImpl
--trace-object-instantiation=org.yaml.snakeyaml.DumperOptions$ScalarStyle
--trace-object-instantiation=org.yaml.snakeyaml.DumperOptions$FlowStyle
--initialize-at-build-time=org.yaml.snakeyaml.DumperOptions$FlowStyle
--initialize-at-build-time=org.yaml.snakeyaml.DumperOptions$ScalarStyle

@UL618PRQ9 It's very likely that a top level expression in your clojure code initializes an object that triggers the initialization of the SecureRandom object

use delay to work around that

you can find where this happens by just following native-image's hints

Warning: Using a deprecated option --delay-class-initialization-to-runtime from command line. Use --initialize-at-run-time.

You need to follow back the chain of initialization using these warnings:

com.sun.jndi.dns.DnsClient caused initialization of this class with the following trace

Oh my good! https://github.com/moclojer/moclojer/actions/runs/6526012390/job/17719305828?pr=153#step:7:192

that's not necessarily all bad, but you have to figure out what causes the init of com.sun.jndi.dns.DnsClient

So add --trace-object-instantiation=com.sun.jndi.dns.DnsClient and --trace-class-instantiation=com.sun.jndi.dns.DnsClient

I managed to get the build to "pass", but I'm doing something wrong - I don't think this is the normal process having to put each library in the runtime init? native-image is asking for it

This will build but won't work. Have you tried my previous suggestion?
