java – Error when compiling plugin filter on ImageJ
This is likely caused by the Path Randomization feature in Mac OSX (maybe because youre running ImageJ from within a mounted dmg file?).
See also this topic on the Image.sc forum:
Quoting from there:
You can disable path randomization by moving ImageJ.app out of the ImageJ folder and then copying it back.
In general, issues with ImageJ (both usage and development) are best discussed on https://forum.image.sc/tag/imagej.
