Could not find TLS ALPN provider; no working netty-tcnative, Conscrypt, or Jetty NPN/ALPN available

Please answer these questions before submitting your issue.

What version of gRPC are you using?

1.13.1

What did you expect to see?

The jar should be running fine.

I am using java 8 to build an executable jar. Below is the java version:

$ /usr/lib/jvm/java-1.8.0-openjdk-amd64/jre/bin/java -version
openjdk version "1.8.0_171"
OpenJDK Runtime Environment (build 1.8.0_171-8u171-b11-2~14.04-b11)
OpenJDK 64-Bit Server VM (build 25.171-b11, mixed mode)

I am using gradle 3.4.1 to generate the jar as follows: /opt/gradle-3.4.1/bin/gradle jar -Dorg.gradle.java.home=/usr/lib/jvm/java-1.8.0-openjdk-amd64/ Below are the dependencies defined in the module-level build.gradle file:

dependencies {
  compile files("$TOOLCHAIN_VERSION_DIR/lib/commons-io-2.6.jar")
  compile files("$TOOLCHAIN_VERSION_DIR/lib/grpc-all.jar")
  compile files("$TOOLCHAIN_VERSION_DIR/lib/java-protobuf.jar")
  compile files("$TOOLCHAIN_VERSION_DIR/lib/jetty.jar")
  compile files("$TOOLCHAIN_VERSION_DIR/lib/log4j-core-2.8.jar")
  compile files("$TOOLCHAIN_VERSION_DIR/lib/log4j-slf4j-impl-2.8.jar")
  compile files("$TOOLCHAIN_VERSION_DIR/lib/netty-tcnative-boringssl-static-2.0.20.Final.jar")
  compile files("$TOOLCHAIN_VERSION_DIR/lib/netty-tcnative-2.0.20.Final.jar")
  compile files("$TOOLCHAIN_VERSION_DIR/lib/picocli-3.8.2.jar")
  compile group: 'com.google.guava', name: 'guava', version: '20.0'
  compile files("$TOOLCHAIN_VERSION_DIR/lib/javassist-3.19.0-GA.jar")
  compile project(':annotation')
}

After building, I am running the jar on an AIX7.2 machine as follows: /usr/java8_64/jre/bin/java -jar agent-1.0.jar

The java version on the AIX machine is as follows:

$ /usr/java8_64/jre/bin/java -version           
java version "1.8.0_191"
Java(TM) SE Runtime Environment (build 8.0.5.26 - pap6480sr5fp26-20181115_03(SR5 FP26))

OMR      - d8c3617
IBM      - 5c4a9f0)
JCL - 20181022_01 based on Oracle jdk8u191-b26

But I am getting the following error while running:

However, it is running fine on an Ubuntu machine. I am running the jar as follows: /usr/lib/jvm/java-1.8.0-openjdk-amd64/jre/bin/java -jar agent-1.0.jar

The java version here is:

$ /usr/lib/jvm/java-1.8.0-openjdk-amd64/jre/bin/java -version
openjdk version "1.8.0_171"
OpenJDK Runtime Environment (build 1.8.0_171-8u171-b11-2~14.04-b11)
OpenJDK 64-Bit Server VM (build 25.171-b11, mixed mode)

What is the problem here and how to solve this?

I had the same problem and I was using a Docker image with a kernel that was incompatible with the netty native libraries needed by my app. I changed the image in my Dockerfile(in my case from “FROM openjdk:8-jre-alpine” to “FROM openjdk:8”) and the issue was fixed.

It must be 64 bit

I still faced the issue while using openjdk:8 and managed to fix it by upgrading to openjdk:11 😊 Java 11 has ALPN available by default.
