Ant ClassFormatException cannot compile JR 3.7.2!

[therockita]

 Hello everybody:

I just did an upgrade from version 3.7.1 to 3.7.2 of JasperReports. Now it comes out that my ant target is not working anymore (from command-line). I tried to find the error in Internet, but I couldn't find anything similar. Any idea would be appreciated.

The error is totally weird! It's related with a class org/eclipse/jdt/internal/compiler/problem/ProblemReporter. 

The funny thing is that if I run the ant target from eclipse, that it's working. My command line ant version is 1.8.0

This is the error I get during the compilation:

Maybe the jdt-compiler.jar file that you are using somehow got corrupted.  Try replacing it with the one from the JR distribution.  Do the samples included in JR work?

The samples didn't work neither.

 

All the problem was apparently caused because of a JAVA update. Indeed everything worked again after I rebooted the PC.

 

I hope to help anyone having the same problem....
