I am able to download the current version of DrJava (drjava-stable-20140826-r5761) onto my computer, an iMac running Yosemite (10.10.2), but am not able to run it once it's downloaded. I get this message:
"DrJava" is damaged and can't be opened.*
Any insights as to what the problem may be? My high school students will (hopefully) be running the IDE on their own computers, which may be Windows or Mac, and could run different OS versions.
Thank you for any assistance.

I have the same problem with the osx/tar file on MacOS Sierra. I also cant open the jar file either.
Hi Dana,
There are two issues concerning the DrJava app that may be causing the
problem.
The DrJava app is bundled with the Apple jar launcher that only works
with Apple Java 6. If you are running Oracle Java 7 or 8, you should
download the .jar file and
execute it. The standard procedure for executing this jar file is to
type the command-line text
java -jar drjava.jar
in a terminal assuming drjava.jar is in the current directory;
otherwise you need to use the path to the drjava.jar file instead of
"drjava.jar".
Mac OS X may be able to open .jar files (using the java application)
by double-clicking but this procedure is problematic. I always use the
command line.
In the recent past, Mac OS X had made FALSE claims about the status of
applications that have not been registered (for a fee) with Apple (alleging
that they are
"damaged". Like most open source software applications, DrJava is NOT
registered. On some Mac OS X systems, this happens with DrJava if you have
Apple Java 6
installed. In this case you can manually open the application (I
think Mac OS X will ask you confirm that you are sure you want to open it)
and Mac OS X will remember
that the application is OK for execution and allow you to open it
normally in the future.
At some point, I will try to bundle the Mac app with the Oracle launcher
but that process is embedded in an ant script that I peruse on a
"need-to-know" basis.
Best,
Corky Cartwright
