: Forgetting to cast or handle Buffer methods correctly when moving between different Java versions (e.g., JDK 8 vs. JDK 9+) can lead to NoSuchMethodError . Recommendations for Implementation
Re-reading or re-writing a buffer that has already been filled or flipped Nio Key - Press Rewind
: When compiling for older environments, explicitly cast the buffer to (java.nio.Buffer) before calling rewind() or flip() to ensure runtime compatibility. : Forgetting to cast or handle Buffer methods
In Java NIO, the rewind() method on a Buffer is used to reset the buffer's position to zero while keeping the limit unchanged, effectively allowing you to the data already contained in the buffer.

: rewind() is ideal when you need to perform a second pass over the same data without modifying the "limit" set by a previous flip() operation.
