How to handle a SIGSEGV with jffi / jnr?

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

# A fatal error has been detected by the Java Runtime Environment:
#
#  SIGSEGV (0xb) at pc=0x0000000000007966, pid=188, tid=189
#
# JRE version: OpenJDK Runtime Environment Temurin-17.0.2+8 (17.0.2+8) (build 17.0.2+8)
# Java VM: OpenJDK 64-Bit Server VM Temurin-17.0.2+8 (17.0.2+8, mixed mode, sharing, tiered, compressed oops, compressed class ptrs, g1 gc, linux-amd64)
# Problematic frame:
# C  0x0000000000007966

What can I do to solve this problem with jffi / jnr? How can I receive more details about the problem?

Answer

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:

ProcessBuilder builder = new ProcessBuilder( "ldd", "/bin/ls" );
Process process = builder.start();
InputStream input = process.getInputStream();
process.waitFor( 5, TimeUnit.SECONDS );
String content = new String( input.readAllBytes() );
LogManager.getConfigLogger().debug( content );
boolean isMuslLibrary = content.contains( "musl-" );

More details are in the issue comments: https://github.com/dbmdz/imageio-jnr/issues/192

Open is the question why loadLibrary not throw an error or how an Java developer can find it.
