Mac OS X 10.10 Problem

[dyvitis]

I recently upgraded to OS X Yosemite and Java 1.8. Upon attempting to start Arduino app, I get an error as follows:
Arduino quit unexpectedly.

Please advise.
Many thanks

I have the same issue. Same error between Arduino versions 1.0.5 and 1.0.6

Hit "More Info" and download and install the Java SE 6 runtime.

[dyvitis]

I would if I was given the option. See attached screen grab.

In the screen grab there is a button called "More info..." like @gregcotten suggests.

[Wdg326]

is there not a better method than to run Java SE 6? ....

Installing a legacy runtime cannot be the answer. The IDE should run with java 8, too.

I've been able to get it working with the 1.5.8 Beta release named "Mac OS X: ZIP file for Java 7" from the download page - it doesn't run if you double-click Arduino.app but I've been able to launch the IDE, compile and program Uno boards.

After copying Arduino.app into my Applications folder, I just did this in the terminal:

cd /Applications/Arduino.app/Contents/Java
java -cp antlr.jar:apple.jar:commons-codec-1.7.jar:commons-exec-1.1.jar:commons-httpclient-3.1.jar:commons-logging-1.0.4.jar:core.jar:ecj.jar:jmdns-3.4.1.jar:jna.jar:jsch-0.1.50.jar:jssc-2.8.0.jar:pde.jar processing.app.Base

(If you're wondering how I figured that long command out, I basically looked at what this launch script in the Linux arduino build does and figured out a similar-looking command)

Here are my java version details:

$ java -version
java version "1.8.0-ea"
Java(TM) SE Runtime Environment (build 1.8.0-ea-b84)
Java HotSpot(TM) 64-Bit Server VM (build 25.0-b25, mixed mode)

I was under the impression Java tries pretty hard to keep new JVM releases compatible with jars targeting older Java versions; I'd be interested to hear, if anyone knows, why the launcher isn't happy with Java 8 given that Processing seems fine with it.

Can you try version "macosx-new" from #2590 (comment) ?

[tcurdt]

macosx-new starts fine for me - but now I already have the legacy java installed already. Not sure how to figure out which runtime it uses.

[ffissore]

Don't know either. The "-new" version should not work with java <= 6. But a way to know which version is using would be nice to have. Maybe a plain lsof | grep -i java ?
