@akudiyar After #438 I'll get this message when I run client with eval requests

    First of all, it is not a bug, it is a warning specific to JDK 17+. See the related issues:

    And this warning should have been already mitigated by the commit 14e051a. So I need a bit more details about the Java version and the build steps.

    This warning is not shown on 1.8 (see the last CI check results for example).

    And this warning should have been already mitigated by the commit 14e051a

    But in warning we can see that msgpack-core-0.9.6 is used.

    WARNING: Illegal reflective access by org.msgpack.core.buffer.DirectBufferAccess (file:/Users/artyom.dubinin/.m2/repository/org/msgpack/msgpack-core/0.9.6/msgpack-core-0.9.6.jar) to constructor java.nio.DirectByteBuffer(long,int,java.lang.Object)

    So I need a bit more details about the Java version and the build steps.

    I ran it on jdk 11
