Doesn't work on OS X 10.11 El Capitan, but installs correctly

[clns]

After installing OS X 10.11 Beta, calling java methods on the java object doesn't work anymore, and a popup opens saying "This application requires the legacy Java SE 6 runtime which is
unavailable for this version of OS X.".

However node-java installs successfully, the only thing I noticed is this message:

2015-06-09 17:09:03.971 xcodebuild[7059:336822] [MT] PluginLoading: Required plug-in 
compatibility UUID E969541F-E6F9-4D25-8158-72DC3545A6C6 for plug-in at path 
'~/Library/Application Support/Developer/Shared/Xcode/Plug-ins/SparkInspectorXcodePlugin.xcplugin' 
not present in DVTPlugInCompatibilityUUIDs

I also checked find-java-home and it's finding the correct jdk:

$ node findJavaHome.js
/Library/Java/JavaVirtualMachines/jdk1.8.0_45.jdk/Contents/Home

I left a comment on stackoverflow, but here it is again:

Please try installing the runtime as discussed here: https://discussions.apple.com/thread/6604985.
Let's hope this installer still works with El Capitan.

Unfortunately that didn't work. I first added the question on SO because I am not sure if the issue is related to (or can be fixed in) node-java, since I noticed the same error with PhpStorm. However I mostly care about node-java to work.

A working solution can be found here.

In short, Oracle's JDK doesn't advertise itself as supporting JNI, so even though node-java links to JAVA_HOME correctly, when the JNI_CreateJavaVM call is made the system sees that the linked JDK doesn't "support" JNI and switches to Java 6 instead.

To fix this I manually enabled JNI by editing
/Library/Java/JavaVirtualMachines/<version>.jdk/Contents/Info.plist and adding JNI as an option in JVMCapabilities:

<key>JVMCapabilities</key>
<array>
    ...
    <string>JNI</string>
</array>

@clns any idea why JDK doesn't advertise itself as supporting JNI?

[clns]

@junqdu No idea.
