SpringBoot Failed to build native image, classes initialized at build time

Hi,

Previously i have filed the issue linked below, but it was being closed. https://github.com/spring-projects/spring-boot/issues/38163

Can i further get some help on this in terms of understanding the issue? I followed your recommendations to trace class initialization, seems all classes initialized because of the following error. Thanks in advance.

org.bouncycastle.jcajce.provider.symmetric.Threefish$Mappings was unintentionally initialized at build time. sun.nio.ch.UnixDomainSockets caused initialization of this class with the following trace:
