Web3j: Dependency Problem with okhttp3

[s1r-mar71n]

Trying to interact with the web3j object results in this error for me:

WARNING: An illegal reflective access operation has occurred

The problem seems to occur at version 4.5.12 and above, the below versions work just fine.

@s1r-mar71n can you share a code snippet so we can replicate please

I solved this issue by making sure i explicitly declare dependencies for the okhttp version used in the web3j version i use, which for web3j-core v4.5.18 was:

<!-- HTTP -->
<dependency>
      <groupId>com.squareup.okhttp3</groupId>
      <artifactId>okhttp</artifactId>
      <version>4.3.1</version>
</dependency>
<dependency>
      <groupId>com.squareup.okhttp3</groupId>
      <artifactId>logging-interceptor</artifactId>
      <version>4.3.1</version>
</dependency>

Before I added the explicit dependencies it has used an older 3.* version of okhttp.

I’ve tried to explicitly add the okhttp dependencies and compiled maven successfully but was unable to run spring boot app.

No errors were generated though..

Anyone facing this issue too?
