How to select java_home output based on provider, when mutiple JDK with same version?

I have oracle and adoptOpen's JDK installed.

$ /usr/libexec/java_home -V
Matching Java Virtual Machines (3):
    11.0.5, x86_64: "Java SE 11.0.5"    /Library/Java/JavaVirtualMachines/jdk-11.0.5.jdk/Contents/Home
    11.0.4, x86_64: "AdoptOpenJDK 11"   /Library/Java/JavaVirtualMachines/adoptopenjdk-11.jdk/Contents/Home
    1.8.0_161, x86_64:  "Java SE 8" /Library/Java/JavaVirtualMachines/jdk1.8.0_161.jdk/Contents/Home

In the past, i switched between jdk11 and jdk1.8 by using:

alias jdk11='export JAVA_HOME=`/usr/libexec/java_home -v11`'
alias jdk8='export JAVA_HOME=`/usr/libexec/java_home -v1.8`'

but I can't see how to select between the two jdk11 providers. java_home -v11 will always get me the Oracle path and the help/manpage do not show any option that I could use to differentiate them.

How can I tell java_home that I want "AdoptOpenJDK 11" and not "Java SE 11"?

java_home does not seem to have a way to filter by provider / vendor. I was able to filter the output of java_home -V to get what you want.

For your particular example,

alias jdk11='export JAVA_HOME=`/usr/libexec/java_home -V 2>&1 > /dev/null | grep "OpenJDK 11" | sed -e "|.*/Library|/Library|"`'
