Solved java disappeared following upgrade to 13.2

[byrnejb]

Following a successful upgrade to 13.2 when running a java application I get the following error:

/usr/local/bin/java -jar /home/byrnejb_hll/Desktop/superbcalc.jar
java: error: no suitable JavaVMs found
java -version
java: error: no suitable JavaVMs found

pkg info -x openjdk
openjdk11-11.0.20+8.1_1
openjdk8-8.382.05.1
openjdk8-jre-8.382.05.1

# javavm
javavm: warning: The use of 'javavm' as a synonym for 'java' is deprecated
java: error: no suitable JavaVMs found

How do I get java back?

Is java/javavmwrapper installed? Does /usr/local/etc/javavms contain anything?

% cat /usr/local/etc/javavms
/usr/local/openjdk11/bin/java
/usr/local/openjdk8/bin/java

I found the problem.

[byrnejb_hll@vhost01 ~ (master)]$ /usr/local/bin/java -jar /home/byrnejb_hll/Desktop/superbcalc.jar
java: error: no suitable JavaVMs found

[byrnejb_hll@vhost01 ~ (master)]$ env | grep -i java

This is, to me, very odd behaviour.

However, java now appears to work for new login sessions without further user action.

Just a note:

pkg info -x openjdk
openjdk11-11.0.22+7.1_1
openjdk17-17.0.10+7.1_1
openjdk21-21.0.2+13.1_1
openjdk8-8.402.06.1_1
openjdk8-jre-8.402.06.1_1

If JAVA_VERSION=11+ then:

java -version
openjdk version "11.0.22" 2024-01-16
OpenJDK Runtime Environment (build 11.0.22+7-1)
OpenJDK 64-Bit Server VM (build 11.0.22+7-1, mixed mode)

If JAVA_VERSION=13+ then:

java -version
java: error: no suitable JavaVMs found

If JAVA_VERSION=17+ then:

java -version
openjdk version "1.8.0_402"
OpenJDK Runtime Environment (build 1.8.0_402-b06)
OpenJDK 64-Bit Server VM (build 25.402-b06, mixed mode)

Which is bizarre
If JAVA_VERSION=21+ then:

java -version
openjdk version "21.0.2" 2024-01-16
OpenJDK Runtime Environment (build 21.0.2+13-1)
OpenJDK 64-Bit Server VM (build 21.0.2+13-1, mixed mode, sharing)

The implication is the the + suffix on JAVA_VERSION stings does not work as expected. So, if the selected JAVA_VERSION is not installed then no java is found. Finally, there is the curious matter of what happens when JAVA_VERSION is set to 17+ . Then the java version switches to openjdk version "1.8.0_402". ???
