Hello,

I have been compiling plugins on a Mac running 10.6.8 with Java 1.6.0_65 from Apple.  I just bought a 10.10.4 Mac and installed the experimental version ImageJ that comes with Java 8.

I am having problems compiling many of the plugins that compiled fine on the old system.

A first question - is how do I get the error log to show?  It either compiles or doesn't with no message.

The second question is specific.  Here is an example of simple string manipulation that works with the old but not with the new:
_________
String filename = "hello";
                IJ.showMessage("test","o" + filename);
_________

It should display "ohello" and does so on the old system, but refuses to compile on the new.  It will work if I do not try to concatenate the two strings with the + sign.  e.g  IJ.showMessage("test",filename); will produce "hello."

So where is my error message and does anyone have ideas on why concatenating strings with "+" works on the old and not the new?

thanks,

Joe v.
