OS X JDK 1.7 failing to load

[jahewson]

I'm using OS X 10.9 with Sun's JDK 1.7 and always get the following error:

JavaVM: Failed to load JVM: /Library/Java/JavaVirtualMachines/jdk1.7.0_45.jdk/Contents/Home/bundle/Libraries/libserver.dylib
JavaVM FATAL: Failed to load the jvm library.
JavaVM: Failed to load JVM: /Library/Java/JavaVirtualMachines/jdk1.7.0_45.jdk/Contents/Home/bundle/Libraries/libserver.dylib
JavaVM FATAL: Failed to load the jvm library.
Segmentation fault: 11

Indeed, the folder /Library/Java/JavaVirtualMachines/jdk1.7.0_45.jdk/Contents/Home/bundle does not exist on my system.

I'm using Sun's JDK 1.7, and do not have Apple's installed. The output of java -version is:

java version "1.7.0_45"
Java(TM) SE Runtime Environment (build 1.7.0_45-b18)
Java HotSpot(TM) 64-Bit Server VM (build 24.45-b08, mixed mode)

At which point in your code the error comes up?

Tested on my system (OS X 10.9 with 1.7.0_45) right now and it works.

[jahewson]

My code was simply:

var java = require("java");
var list = java.newInstanceSync("java.util.ArrayList");

The error occurs on line 2 (determined by inserting a console.log) there is no stack trace.

[joewhite86]

Seems like the java environment isn't set up correctly on your system. The only place I found this file on mine is: /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Libraries/libserver.dylib, which is the pre-installed java version that came with previous versions of OS X.

What are your Java environment variables? (JAVA_HOME, ...)

[jahewson]

OS X 10.9 (Mavericks) does not come with Java installed. The Apple version of Java 1.6 is available as an update but not Java 1.7, which must be downloaded from Oracle.

I do not have any environmental variables set regarding Java, there is no JAVA_HOME or Java directories in the PATH as Oracle's installer did not set them.

I think the problem may be that node-java assumes that Apple's version of Java is installed, which is not necessarily true.

[joewhite86]

No node-java works with both, pre-installed and others. If you upgraded from previous versions of osx you can indeed have the pre-installed jdk under /System/Library.

Try setting JAVA_HOME

[jahewson]

I have a fresh installation of Mavericks, not an upgrade. node-java needs to work out of the box with Oracle Java 7...

[jahewson]

I've done some investigating - as you said the JDK under /System/Library/Java is present on Mavericks, but I think it's intended for system use (or is this just where Apple keeps its JDK?):

ls /System/Library/Java/JavaVirtualMachines
1.6.0.jdk

The user-accesible (or just Oracle?) JDKs are under /Library/Java and I only have Oracle's JDK 1.7:

~$ ls /Library/Java/JavaVirtualMachines/
jdk1.7.0_45.jdk

The Oracle JDK 7's Home directory contents is:

~$ ls /Library/Java/JavaVirtualMachines/jdk1.7.0_45.jdk/Contents/Home/

THIRDPARTYLICENSEREADME.txt     release
bin                 src.zip
db

as you can see, there is no bundle directory, which relates to the original error message.

I think find-java-home would help out here.

@jahewson Can you clone my fork locally and try building that? Here's the URL: https://github.com/jsdevel/node-java.git

I currently have PR for issue #94 open and I believe it will solve issues like this.

@jahewson Now that 0.3.0 is published, can you try installing again with 0.3.0?

[TheSpyder]

I'm still seeing this with 0.3.2, OS X 10.9.2.

shinji:corpus spyder$ echo $JAVA_HOME
/Library/Java/JavaVirtualMachines/jdk1.7.0_55.jdk/Contents/Home
shinji:corpus spyder$ node corpus.js 
<startup output>
No Java runtime present, requesting install.

I'm also using java.newInstanceSync.

[jsdevel]

@joeferner should we add libserver.dylib to postInstall.js?

[joeferner]

That would probably make sense. Anyone have OSX to try it on?

[TheSpyder]

I'm happy to test anything if you can give me a patch or tell me how to modify my local install :)

[jsdevel]

@TheSpyder can you try adding git+https://github.com/jsdevel/node-java.git#a4c47f938903957f578c7f228f4aad34b6cfdb32 in your package.json for java?

node(94131,0x7fff7d3e0310) malloc: *** error for object 0x103f7e7c0: pointer being freed was not allocated
*** set a breakpoint in malloc_error_break to debug
Abort trap: 6

well that was interesting :)

Do I need to run a particular command to get more detail?
