Java 8:java.lang.NoSuchMethodError: java.nio.ByteBuffer.limit(I)Ljava/nio/ByteBuffer

[Former user]

Hi IJabz,

Please cast java.nio.ByteBuffer instances where necessary to java.nio.Buffer to avoid NoSuchMethodError when running on Java 8.

The Java 11+ ByteBuffer classes introduces overloaded methods with covariant return types for the following methods used by the driver:

• position
• limit
• flip
• clear

Without casting, exceptions like this are thrown when executing on Java 8 and lower:

 java.lang.NoSuchMethodError: java.nio.ByteBuffer.limit(I)Ljava/nio/ByteBuffer

This is because the generated byte code includes the static return type of the method, which is not found on Java 8 and lower because the overloaded methods with covariant return types don't exist.

Example:

buf.position(newPosition);

((Buffer) buf).position(newPosition);

Summary:

works without problems if all references are changed.

Best regards

Please provide a pull request if you want fixed as this is of little interest to me since I only use with Java 11 onwards.
