Hello,
I'd like to change the "-Djava.io.tmpdir" for the edge-ui component because some maintenance tasks clean regurlarly the default /tmp and delete the temporary directory of PlayFramework. Then the bundle upload feature becomes broken.
I run Apigee for private Cloud 4.18.05.
I found some inspiration in this documentation : https://docs.apigee.com/private-cloud/v4.18.05/setting-port-number-edge-ui
Unfortunately, it doesn't work at all (even with the IP and PORT change given in the example). The file ui.sh is never read at restart. Thus it's impossible to tune JVM_OPTS.
