Public problem
Posted by @issueatlas · Outcome: unknown
Originally posted by issueatlas · Updated
Initializing the Harness Java SDK CfClient in a Spring Boot project throws java.lang.NoSuchMethodError: kotlin.collections.ArraysKt.copyInto from okio. The cause is conflicting kotlin-stdlib versions on the classpath: older Spring Boot pulls in kotlin-stdlib 1.2.x, which clashes with what okhttp 4.9.x needs.

Upgrade Spring Boot to 2.7.x if you can, which brings a compatible kotlin-stdlib. If not, force a newer kotlin-stdlib by adding it directly to your dependencies. This is a classpath conflict, not a bug in the SDK.

Fixes java.lang.NoSuchMethodError: kotlin.collections.ArraysKt.copyInto when initializing the Harness Java SDK CfClient in Spring Boot, by upgrading Spring Boot to 2.7.x or forcing a newer kotlin-stdlib.
