Running Java 8 ImageJ headless

Avital Steinberg
Hi,
I have a problem running ImageJ 1.51i java 1.8.0_112 (64 bit) in the
headless mode on LinuxMint 17 Qiana. I posted this question also in the
ImageJ developers forum, but I still haven't been able to solve this issue.
When I run the following command:

[path_to_ImageJ]/ij.jar helloImageJ.py -b &

It works. (helloImageJ.py just prints hello to the console)

On the other hand, when I write the following command:

[path_to_ImageJ]/ImageJ helloImageJ.py -b &

I get the following error message:

Java HotSpot(TM) 64-Bit Server VM warning: ignoring option
PermSize=128m; support was removed in 8.0
Unrecognized option: -b
Warning: falling back to System JVM
Unrecognized option: -b
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

Any idea how to fix this problem? I need to work in batch mode, because the
goal is to obviously run my image analysis script in headless mode. (rather
than the hello world program)

Thanks,
Avital

Hi Avital,

When asking questions in multiple places, it is always good to cross-link,
so people can follow the whole discussion.

The forum thread is here:
http://forum.imagej.net/t/a-problem-running-imagej-in-headless-mode/3909

And as I said there, I will be releasing a new version of ImageJ2 later
this week which fixes the issue you are having with the "--ij2 --headless
--run" syntax.

Regards,
Curtis

Thanks, Curtis - sorry for forgetting to cross-link, multiple people were
making various requests from me simultaneously.

I'm looking forward to using the new release of ImageJ2.

See you in Portugal,
Avital
