[ImageJ-devel] creating io.scif.img.ImgOpener currently fails in Fiji

[Tobias Pietzsch]

Hi,

Currently
new io.scif.img.ImgOpener();
fails with
java.lang.IllegalArgumentException: Invalid service: net.imagej.legacy.LegacyAppEventService

To reproduce run
new io.scif.img.ImgOpener();
in Beanshell interpreter.

The exception displayed in Beanshell interpreter is a bit non-helpful.
Benjamin Schmid noticed the error, when it occurred in BigDataViewer’s ExportSpimSequencePlugIn.
Here is the exception from that, which is a bit more detailed
