What version of gRPC are you using?
1.13.1
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))
IBM J9 VM (build 2.9, JRE 1.8.0 AIX ppc64-64-Bit Compressed References 20181106_401576 (JIT enabled, AOT enabled)

OMR - d8c3617

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?
回答1:
It could be that: https://github.com/grpc/grpc-java/blob/master/SECURITY.md#tls-with-netty-tcnative-on-boringssl
I added runtime 'io.netty:netty-tcnative-boringssl-static:2.0.25.Final' in my build.gradle and it worked
