            How to handle a SIGSEGV with jffi / jnr?
            Asked 2022-Mar-24 at 09:28

            The Java VM crash with a SIGSEGV in a docker container. On all other systems it is working as expected.

            The cause of the crash on Linux was a inkompatible native libraries for the target OS. The native library was compiled with glibc and the OS with the crash use musl. It was not a bug in any of the libraries.

            To solve the problem we bundle now a second version of the library. And differ with the follow code:

            Docker image build failed on Mac M1 chip
            Asked 2022-Feb-28 at 21:55

            I'm trying to build a simple docker image, inside a maven project, adding the image build as part of the maven build process:

            It looks like the dockerfile-maven-plugin uses a runtime based on x86 architecture and won't run on Apple M1 (Arm).
            The plugin is now inactive so you should try something else, for example the fabric8-maven-plugin

            I am very new to apache spark and I just have to fetch a table from cassandra database, Below I have appended the data to debug the situation, Please help and thanks in advance. Cassandra Node: Spark Node:

            You can't use connector compiled for Scala 2.11 with Spark 3.2.0 that is compiled with Scala 2.12. You need to use appropriate version - right now it's 3.1.0 with coordinates com.datastax.spark:spark-cassandra-connector_2.12:3.1.0

            P.S. Please note that although basic functionality will work, more advanced functionality won't work until the SPARKC-670 is fixed (see this PR)

            Could not load FFI provider when using module-info.java

            my Linux Java application uses bluetooth devices. I use this library in order to communicate with bluez stack : https://github.com/hypfvieh/bluez-dbus.

            It worked very well until I added module-info.java to my client code. Suddenly I got this error:
