STScI Science Cluster users will need to edit their .envrc file
to make sure JAVA is in their path. To do this, edit the .envrc file in
your home directory and make sure the line
Package: JDK12
is in the file and does not have a # character before it. This
line needs to be in the file AFTER the line
Type: User
line near the top of the file. After making these changes, log
out and log back in.
