[Impact]
Maven 3.6.3-1 fails to run with OpenJDK 16 and 17.
Users building for OpenJDK 17 are unable to use the packaged Maven.
This bug was fixed in Maven 3.6.3-2 (and above)[1]
Packages maven and guice need to be updated in focal to fix this bug.
[Test Plan]
For the version in the release pocket and the version in the proposed pocket, use maven to compile https://github.com/socialsoftware/quizzes-tutor:
$ sudo apt install openjdk-17-jdk maven=$VERSION
$ git clone https://github.com/socialsoftware/quizzes-tutor.git
$ cd quizzes-tutor
$ cd backend
$ mvn clean compile
This should fail for the version in the release pocket, with the error below, and succeed for the version in the proposed pocket.
Sample test script:
```
#!/bin/bash
set -ex
lxc launch ubuntu:focal tester
lxc exec tester -- /bin/sh -c "echo deb http://archive.ubuntu.com/ubuntu/ focal-proposed restricted main multiverse universe > /etc/apt/sources.list.d/ubuntu-focal-proposed.list"
sleep 10
lxc exec tester -- /bin/sh -c "apt-get update && apt-get upgrade -y"
lxc exec tester -- apt-get install -y maven openjdk-17-jdk-headless
lxc exec tester -- git clone https://github.com/socialsoftware/quizzes-tutor.git
lxc exec tester -- /bin/sh -c "cd quizzes-tutor/backend && mvn clean compile"
lxc exec tester -- java -version
lxc delete -f tester
```
Test Maven against other openjdk versions in focal:
```
#!/bin/bash
set -ex
for x in 8 11 13 16 17 21; do
echo ==== test java version $x ====
lxc launch ubuntu:focal tester
lxc exec tester -- /bin/sh -c "echo deb http://archive.ubuntu.com/ubuntu/ focal-proposed restricted main multiverse universe > /etc/apt/sources.list.d/ubuntu-focal-proposed.list"
sleep 10
lxc exec tester -- /bin/sh -c "apt-get update && apt-get upgrade -y"
lxc exec tester -- apt-get install -y maven openjdk-$x-jdk-headless
if [ $x == "8" ]; then
lxc exec tester -- update-alternatives --set java /usr/lib/jvm/java-$x-openjdk-amd64/jre/bin/java
else
lxc exec tester -- update-alternatives --set java /usr/lib/jvm/java-$x-openjdk-amd64/bin/java
fi
lxc exec tester -- update-alternatives --set javac /usr/lib/jvm/java-$x-openjdk-amd64/bin/javac
lxc exec tester -- git clone https://github.com/mkyong/maven-examples
for module in java-multi-modules java-project maven-code-coverage maven-mutation-testing maven-profiles maven-static-code-analysis maven-unit-test; do
lxc exec tester -- /bin/sh -c "cd maven-examples/$module && mvn clean compile"
done
lxc exec tester -- java -version
lxc delete -f tester
done```
[Where problems could occur]
Guice:
- this SRU installs a new artifact - guice-no-aop-4.2.1.jar. There is no other impact for this package.
Maven:
- guice.jar is replaced with guice-no-aop.jar. This is optional[2] functionality and Apache's release of maven 3.6.3 includes `guice-4.2.1-no_aop.jar`[3]
- Maven should be tested against Java versions present in focal, e.g. test building a sample project:
```
#!/bin/bash
set -ex
for x in 8 11 13 16 17; do
echo ==== test java version $x ====
lxc launch ubuntu:focal tester
lxc exec tester -- /bin/sh -c "echo deb http://archive.ubuntu.com/ubuntu/ focal-proposed restricted main multiverse universe > /etc/apt/sources.list.d/ubuntu-focal-proposed.list"
sleep 10
lxc exec tester -- /bin/sh -c "apt-get update && apt-get upgrade -y"
lxc exec tester -- apt-get install -y maven openjdk-$x-jdk-headless
if [ $x == "8" ]; then
lxc exec tester -- update-alternatives --set java /usr/lib/jvm/java-$x-openjdk-amd64/jre/bin/java
else
lxc exec tester -- update-alternatives --set java /usr/lib/jvm/java-$x-openjdk-amd64/bin/java
fi
lxc exec tester -- update-alternatives --set javac /usr/lib/jvm/java-$x-openjdk-amd64/bin/javac
lxc exec tester -- git clone https://github.com/mkyong/maven-examples
for module in java-multi-modules java-project maven-code-coverage maven-mutation-testing maven-profiles maven-static-code-analysis maven-unit-test; do
lxc exec tester -- /bin/sh -c "cd maven-examples/$module && mvn clean compile"
done
lxc exec tester -- java -version
lxc delete -f tester
done```

*Summary*
Maven 3.6.3-1 apparently fails to run with OpenJDK 16. It seems to be a bug and was fixed in Maven 3.6.3-2 (and above) according to https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=980467.
*Expected behaviour*
I expect to be able to use maven with all currently supported General Availability Java versions.
*Observed behaviour*
I installed OpenJDK 16 (via PPA, see version above) and tried to compile a Maven project, producing the following output:
```
$ mvn compile
[ERROR] Error executing Maven.
[ERROR] java.lang.IllegalStateException: Unable to load cache item
[ERROR] Caused by: Unable to load cache item
[ERROR] Caused by: Could not initialize class com.google.inject.internal.cglib.core.$MethodWrapper
$ echo $?
1
```
