When trying to run DevSuite 1.4 online installer on Mac OS X 10.10, there are several serious usability problems related to getting Java installed:

1. The installer keeps triggering a pop-up to install java. After the pop-up is dismissed is reappears within a few seconds making it difficult to do anything with the install. This appears to be triggered by running /usr/bin/java. So presumably, during the download selection screen, the installer is repeatedly trying to run /usr/bin/java triggering this loop.
2. If the user follows the pop-up, and installs Oracle Java, it appears to install a Java SE that works as a plugin in Safari, but /usr/bin/java still triggers no Java installed. (The Java download that results from this is Oracle jre-8u131-macosx-x64.dmg)
3. Note: The above means even though the instructions to install Java have been followed, and some version of java has been installed and verified in the browser, the installer has been exited and restarted, the same thing happens again!
4. There is a link in the installer to click for Oracle Java, but it's not clear if that link goes to a valid java or the incessant pop-up behavior is preventing that link from working.
5. Unselectiong Dev Studio does NOT stop the pop-up from incessantly reoccurring.

This makes for an extremely frustrating user experience. While some of it might be due to Oracle's packaing/terminology around Java, the DevSuite installer appears to be causing the problems.

1. This might be related to JBDS-4402, where it appears the installer at least on windows attempts to keep rescanning when window events occur rather than having some sort of flow to cause a rescan.
2. I haven't tried other versions of OS X, but at least on 10.10.5, /usr/bin/java causes this problematic pop-up. Suggest the installer find another way of testing if java is installed and what version on Mac OS.
