java7

[Eric Leroy-2]

Hi
Happy new year to everybody.
I am using Fiji and ImageJ on a mac running under 10.9.1 with both java 6 and java 7 installed. When I lauch either Fiji and ImageJ I noticed that the java version that is used is java 6. If I lauch ij.jar from the command line it is java 7 that is used. I would like to know how to use java 7 when the application is launched by double click. Do you know how to do this ?

Thank you for your help

Regards

Eric

Use the --java-home command line option.

See the Fiji FAQ here:

Hope that helps,

Hi,

I am afraid that the --java-home feature is currently nonfunctional on OS X
10.8 and 10.9. I have a topic branch to fix it but it is not quite ready to
be merged:

https://github.com/imagej/imagej-launcher/pull/1

I will reply back with more details when I am back In the office this week.

Regards,
Curtis

For the moment, the ImageJ launcher does not allow using Java 7 on MacOSX.
The reason is that for a long time, it was not even clear where Java would
go on MacOSX and then it was clear that it was going to be buggy for a
while and now it is clear that Java 7 would force everybody to upgrade to
the newest MacOSX (and of course, the newest Apple hardware).

Having said that, Curtis Rueden worked on this issue quite a bit and now
it patiently awaits the time when yours truly will be able to make sure
that things still work with Java 1.6 (and even Java 1.5).

Hopefully I'll come around to taking care of that next week.

Ciao,
Johannes
