server version command ignores JAVA_HOME set in server's server.env

[ninadaa]

Describe the bug
The server version <serverName> command ignores the JAVA_HOME variable that is set in the server's server.envfile.
Instead it prints out the java version info of the java installation set by JAVA_HOME variable in shell environment (bash).

Steps to Reproduce

• set JAVA_HOME in shell envionment (e.g. set to Semeru 8 installation)
• create server myServer and add server.env in ${WLP_INSTALL_DIR}/usr/servers/myServer/server.env
• set JAVA_HOME (e.g. set to Semeru 11 installation) in ${WLP_INSTALL_DIR}/usr/servers/myServer/server.env
• run ${WLP_INSTALL_DIR}/bin/server version myServer

Expected behavior
When I run server version <serverName> I expect it to display the version info related to the java installation I specified in the server.env of the server.

Diagnostic information:

• OpenLiberty Version: 23.0.0.3

Additional context
Works as expected if I change the server script to:

  version)
    #installEnv
    serverEnv
    javaCmd '' --version

Just to confirm... server start does pickup the correct version right? as seen in the logs...
But I have confirmed this issue with the server version command. = We will investigate.

@ninadaa I did confirm if a server.env file is added to ${wlp.install.dir}/etc/server.env. those values are picked up by the server version command. still investigating as we do see some inconsistencies...

@cbridgha yes, server start picks the correct Java, only server version does not.
