Hello,
We are attempting to upgrade an application to the Java 7 platform. This is a
web-based app using Spring 3.0.5 and AspectJ compile time weaving. We use Ant
to build and set our iajc task to target the 1.7 JDK. Everything builds but we
are experiencing runtime errors in the application that I'm having trouble
understanding and believe might be related to the AspectJ compiler:
java.lang.NoClassDefFoundError:

Line 79 of PlantMatrixServiceImpl:
OperatingModeCalculator calculator = new OperatingModeCalculator(matrix);
The DomainObject class it is complaining about is a generic class with a
definition like:
public abstract class DomainObject<PK extends Identity> implements
Serializable, Comparable<DomainObject> { ... }
The OperatingModeCalculator class above does not extend DomainObject so not
sure why the error is listed as coming from there.
com.utilivisor is our package and the code is definitely there in a JAR in the
WEB-INF/lib folder so I am confused. Any ideas how to fix or further
troubleshoot this? More info about our environment:
- Oracle 64-bit JDK 1.7.0_09-b05 on Linux
- Tried AspectJ 1.7.1 and latest dev
- Spring 3.0.5, tried 3.0.7 and 3.1.0
