David,

you need to set the -ea flag when you start ImageJ (Java VM). Compile-and-Run does not stop/start the JVM. For example, on my WinXP/Sun-JVM system I simply changed the file ImageJ.cfg to:

.
jre\bin\javaw.exe
-ea -Xmx594m -cp ij.jar ij.ImageJ

Here is an example:
//---------------------------------------------------
import ij.IJ;
import ij.plugin.PlugIn;

public class JavaCheckAssertions implements PlugIn {
 public void run(String arg0) {
  assert false : "YES, assertions are activated!";
  IJ.log("Assertions are turned OFF (use -ea switch to start IJ)");
 }
}
//---------------------------------------------------

Works fine here.

But how do I do this when using ImageJ's 'Compile and Run"?
