Environment details

OS type and version: Linux 3.0.101-108.108-default x86_64 Java version: Java(TM) SE Runtime Environment (build 1.8.0_66-b17)

Steps to reproduce

  1. It's a simple subscriber taken from GCP GitLab.
  2. The Unix box where ever I am deploying, I shouldn't be installing or changing any softwares on it, just copy the spring boot jar and run the app. It should work as is.

Any additional information below

The same Spring boot executable jar works perfectly fine on Windows, but if I run the same jar on Unix environment throws this error. I have used the maven dependencies of netty and other native libraries as shown in the code below. Still throws the same error.

rpm -qa | fgrep glibc
glibc-32bit-2.11.3-17.110.33.1
glibc-2.11.3-17.110.33.1
glibc-devel-2.11.3-17.110.33.1
glibc-locale-32bit-2.11.3-17.110.33.1
glibc-locale-2.11.3-17.110.33.1
glibc-devel-32bit-2.11.3-17.110.33.1
glibc-i18ndata-2.11.3-17.110.33.1

Observation

I suspect I need to downgrade my GCP library version to make GLIBC version compatible, with the current GCP versions what ever I am using in pom.xml, I see below errors in logs (complete stacktrace is shown at the bottom):

Caused by: java.lang.UnsatisfiedLinkError: /tmp/libconscrypt_openjdk_jni-linux-x86_6416587725916100000.so: /lib64/libc.so.6: version `GLIBC_2.14' not found (required by /tmp/libconscrypt_openjdk_jni-linux-x86_6416587725916100000.so)

  • Your actual issue might be different. The messages are at INFO level and there are messages in parens "(this may be normal)". If you suppress debug logs what error do you see? – San P Jul 27 '22 at 18:53
  • Have you configured your Java environment to work with GCP projects as follows in [this documentation](https://cloud.google.com/java/docs/setup#optional_install_maven_or_gradle_plugin_for_app_engine)? – Osvaldo Jul 27 '22 at 22:23

You need to use a kernel which was built against GLIBC_2.14 or GLIBC_2.12 - GLIBC_2.11 is too old.

It not only complains about GLIBC_2.14:

UnsatisfiedLinkError: /tmp/libconscrypt_openjdk_jni-linux-x86_6416587725916100000.so: /lib64/libc.so.6: version `GLIBC_2.14' not found (required by /tmp/libconscrypt_openjdk_jni-linux-x86_6416587725916100000.so)

But it also complains about GLIBC_2.12:

UnsatisfiedLinkError: /tmp/libio_grpc_netty_shaded_netty_tcnative_linux_x86_646976970630165030878.so: /lib64/libpthread.so.0: version `GLIBC_2.12' not found (required by /tmp/libio_grpc_netty_shaded_netty_tcnative_linux_x86_646976970630165030878.so

You need to use both versions, which need the same GLIBC requirement as the kernel's GLIBC version offers. So you need a kernel with GLIBC_2.14 or GLIBC_2.12 to begin with. Mixing these versions is definitely not possible. This seems similar, but there may be two version issues.
