After I remove it works fine,

<dependency>
      <groupId>net.snowflake</groupId>
      <artifactId>snowflake-jdbc</artifactId>
      <version>3.14.4</version>
    </dependency>

5. What did you expect to see?
   if you change the snowflake-jdbc to 3.13.18, it works fine,

<dependency>
      <groupId>net.snowflake</groupId>
      <artifactId>snowflake-jdbc</artifactId>
      <version>3.13.18</version>
    </dependency>

when we use 3.13.19 or later, we get Unsupported class file major version 59

Hi @sunscorch
I tried to build using your pom.xml - indeed it causes the problem and it's because of Java 15 classes (or higher) from META-INF/versions:

META-INF/versions/15/org/bouncycastle/jcajce/provider/asymmetric/edec/SignatureSpi$Ed25519.class: java.lang.IllegalArgumentException: Unsupported class file major version 59

I found that to solve that you can use higher version of shade-maven-plugin e.g. 3.4.1 (as it is used in snowflake-jdbc)
It's not a bug in snowflake-jdbc

thanks a lot for your information, great help from your side
