Performance of 'direct buffer constructor' #14971
-
|
Hi We are planning to migrate our project from Java8 to Java11/17, while using netty (version 4.1.60) We see that in Java8, 'direct buffer constructor' is available, where in Java11 is not. We don't know if having this function disabled can impact performance, do you have any experience in this situation ? Thanks |

It's not available because Java started to lock down reflective access to JDK internals. Netty will use JNI, Unsafe, or create buffers with cleaners attached instead, depending on the use case. |

You can add an export to allow the usage of it again. If possible is it worth enabling it? |
