I have just upgraded my imagej and replaced the ij file in the imagej
folder with the new ij file. However now all my plugins don't work I
just get a message when I try to run them saying:

"This JVM does not include the javac compiler. Javac is included with
the Windows and Linux versions of ImageJ that are bundled with Java"

What have I done??
