Apr 17, 2018 - How to Install JDK on Mac OS X 3. Renamed to Java 1 in JDK 1.0.2. Java SE 8 (JDK 1.8) (March 18, 2014): included support for Lambda. The instructions for installing the JDK (Java Development Kit) are a subset of the instructions for installing just the JRE, because Oracle provides an installer for the JDK. Go to the Oracle Java downloads page and download the JDK installer.
Java/Mac FAQ: Where is JAVA_HOME located on Mac OS X (macOS) systems? JDK location This has changed over time, but if you're using Mac OS X 10.9 or newer, your JDK/SDK JAVA_HOME location for Java 8 will be something like this: /Library/Java/JavaVirtualMachines/jdk1.8.0_181.jdk/Contents/Home For Java 7 it was also in the same area: /Library/Java/JavaVirtualMachines/jdk1.7.0_51.jdk/Contents/Home/ Of course that will vary by the JDK version you have installed.
I would be surprised if it were possible, without editting the Info.plist. That is what I have been doing ever since Mavericks with the Apple 1.6 JVM being optional, I don't have that installed.
It is little trouble for EAP upgrade. The man gotcha is: when installing from an entirely new.dmg, rather than a patch, run the Application once and refuse the option of installing the Apple 1.6 JVM, then edit the Info.plist and run IDEA again. Otherwise Mavericks complains that the Application is corrupted. Perhaps someone else know better, I don't know. I tried to use both JVM 7 & 8 w/ IntelliJ.
The result is that the Mac freezes in both cases after some hours running IntelliJ w/ JVM 7/8. Of course I can't exactly proof that this is the reason but I tried it several times. Usually I have an uptime of > 30d. Running IntelliJ w/ JVM 7/8 reduced the uptime *every time* to. For what it is worth, I've not really had such a problem. I have been running the EAPs under 1.7 pretty much since the Info.plist setting was first noted here.
Like everyone, I expect, using 1.7 or not, I have had occasonal problems. In general & certainly at the moment I don't think I see failures after less than two days, I would guess I most typically run for a couple of weeks without problem.
Gmail asked for passwork on mac imessage not working. Eventually, after entering my password enough it stopped prompting me for it (but didn't activate iMessage). When I tried to activate it, it once again asked for my password, and then accepted it. Everything seemed to be fine: all of my old conversations were there and visible.
Of course, I may noy be using the EAP with a different mix of feature use, not to mention plugins. In my case I work mainly in Java with Play framework 1 & Scala with Play framework 2. Of course, I do hope that the problem you see gets fixed. Just another point of reference.
