Summary

Using the first release of java 18, it identifies itself as version 18-ea. This creates a problem in the method getJavaMajorVersion where - is not supported. This then creates a number exception.

 

https://github.com/mongodb/mongo-java-driver/blob/master/driver-core/src/main/com/mongodb/internal/connection/tlschannel/util/Util.java

 public static int getJavaMajorVersion() {
    String version = System.getProperty("java.version");
    if (version.startsWith("1."))

{       version = version.substring(2, 3);     }

else {
      int dot = version.indexOf(".");
      if (dot != -1)

{         version = version.substring(0, dot);       }

    }
    return Integer.parseInt(version);
  }
