Because the shell does not use JAVA_HOME but PATH for lookup of executables.

Might be.  Might also be that one Java installation put their executable there.  Bottom line, you better make sure the proper executables from an installation directory are used.  I typically have scripts which will honor JAVA_HOME and pick the proper executables so I can easily switch Java versions.
