Not able to switch Java version to Java 17

by |Published

I have installed Amazon Corretto Java 17 from here.

However, I am not able to switch the Java version to Java 17.

Following are the steps I have already tried:

1.

export JAVA_HOME=`/usr/libexec/java_home -v17`
  1. export JAVA_HOME=/Library/Java/JavaVirtualMachines/amazon-corretto-17.jdk/Contents/Home
  2. I have also check the highest version of Java using below command:
    /usr/libexec/java_home and it shows correct Java 17 version:
    /Library/Java/JavaVirtualMachines/amazon-corretto-17.jdk/Contents/Home
  3. I have also checked all the versions of Java installed on my machine using command /usr/libexec/java_home -V and it correctly shows Java 8, 11, and 17:
17.0.1 (x86_64) "Amazon.com Inc." - "Amazon Corretto 17" /Library/Java/JavaVirtualMachines/amazon-corretto-17.jdk/Contents/Home

11.0.9.1 (x86_64) "Amazon.com Inc." - "Amazon Corretto 11" /Users/harsh.pamnani/Library/Java/JavaVirtualMachines/corretto-11.0.9.1/Contents/Home

1.8.0_275 (x86_64) "Amazon" - "Amazon Corretto 8" /Library/Java/JavaVirtualMachines/amazon-corretto-8.jdk/Contents/Home
/Library/Java/JavaVirtualMachines/amazon-corretto-17.jdk/Contents/Home
  1. I also added JAVA_HOME exports mentioned in step-1 and step-2 to .zshrc and .bash_profile as well.
  2. I have followed multiple questions on StackOverflow and multiple
    blogs as well. For example,

  1. I am using jenv to switch between different java versions. Even jenv is not able to find Java 17. I used jenv versions and following is the output:
system
  1.8
  1.8.0.275
  11
  11.0
* 11.0.9.1 (set by /Users/harsh.pamnani/.jenv/version)
  corretto64-1.8.0.275
  corretto64-11.0.9.1

Even after following all the steps above when I do java --version, it is still set to Java 11:

openjdk 11.0.9.1 2020-11-04 LTS
OpenJDK Runtime Environment Corretto-11.0.9.12.1 (build 11.0.9.1+12-LTS)
OpenJDK 64-Bit Server VM Corretto-11.0.9.12.1 (build 11.0.9.1+12-LTS, mixed mode)

Could someone please help me understand if I am missing anything here. Thank you.
