$JAVA_HOME doesn't direct to latest java installation – CentOS

I have a CentOS 7 VM. I recently installed 1.8.0_251 jdk version. Previous jdk version was 1.8.0_172. I inserted the following lines to a custom.sh script in /etc/profile.d/ to affect the new java version system-wide.

export PATH=/usr/java/jdk1.8.0_251-amd64/bin:$PATH
export JAVA_HOME="/usr/java/jdk1.8.0_251-amd64/"

I get the java version correctly.

[igwstuser@integrator1 ~]$ java -version
java version "1.8.0_251"
Java(TM) SE Runtime Environment (build 1.8.0_251-b08)
Java HotSpot(TM) 64-Bit Server VM (build 25.251-b08, mixed mode)

Still I get the early version when JAVA_HOME is invoked through igwstuser. When JAVA_HOME is invoked through root user, I get the correct version. How can I resolve this?

[igwstuser@integrator1 ~]$ echo $JAVA_HOME
/usr/java/jdk1.8.0_172-amd64/
[igwstuser@integrator1 ~]$ sudo su
[root@integrator1 igwstuser]# echo $JAVA_HOME
/usr/java/jdk1.8.0_251-amd64/

    • Did you check your bashrc as “igwstuser”?
    • Is it pointing to the right java version?

    Just do this and check which java version it is pointing to with cat ~/.bashrc

    If you see some other java version then using text editor set correct value for export JAVA_HOME=

    After making necessary changes don’t forget to source bashrc to make changes available with source ~/.bashrc

    /etc/profile.d is for global users, for Linux env, this file runs first, then ~/.bash_rc and ~/.bash_profile for individual users.
    You need to check this user integrator1‘s ~/.bashrc and ~/.bash_profile, is there a JAVA_HOME set. If it is, change it to your latest JAVA_HOME. Then source it.

    Permissions on /etc/profile.d/custom.sh need to be open so all users can read the file during login. Only root can read it if only root is getting the setting.
