Hi All,
I'm creating a single instance of ImageJ (ImageJ2) in my program and using this
instance to access the various services of ImageJ2. However, in previous work
with Curtis Rueden, we found we had to add the following static code to the
class which I use to access this single ImageJ instance so that the services
load (I believe because of the presence of the ImageJ1 jar included along with
the ImageJ2 group of jars).
static
{
DefaultLegacyService.preinit();
}
However I ran into the following issue.
With Java 1.6 and 1.7 installed on my system everything worked great. No
issues. I downloaded and installed Java 1.8 and then I received the following
error upon reaching this preinitialization code.
java.lang.IllegalArgumentException: Cannot handle app name in
ij.ImageJ's public <init>(java.applet.Applet applet, int mode)
at imagej.legacy.CodeHacker.replaceAppNameInCall(CodeHacker.java:498)
at imagej.legacy.LegacyExtensions.insertAppNameHooks(LegacyExtensions.java:591)
at imagej.legacy.LegacyExtensions.injectHooks(LegacyExtensions.java:516)
at imagej.legacy.LegacyInjector.injectHooks(LegacyInjector.java:154)
at imagej.legacy.LegacyInjector.injectHooks(LegacyInjector.java:57)
at imagej.legacy.DefaultLegacyService.<clinit>(DefaultLegacyService.java:109)
I then used the old but useful "Java Preferences.app" to change the default
order of preferred jres. I moved 1.7 ahead of 1.8 and the application worked
again. Then I put 1.8 above 1.8 again and the problem no longer occurred. I
can't repeat the problem on my computer but another person is having the same
issue. I'll likely have him do what I did but this seems like a silly work
around. Do you know what might be the root cause? Am I just using the ImageJ2
project with inappropriate/unsupported jre's even though it eventually works
under 1.8.
Thanks,
Jay
