Quoting Niclas Hedhman <[email protected]>:
Gangs,I have been trying to locate why the following code snippets compile and works on Java6, but doesn't compile on Java5. Note that the generics are for the method only. We have it declared at the class level (on the called class) in which case it compiles. Any pointer to what is going on is greatly appreciated. If we can't figure this out, I think we would need to move Qi4j to Java 6 even though it doesn't make sense for any other reason. public abstract class AbstractModifierModel { public <ThrowableType extends Throwable> void visitModel( ModelVisitor<ThrowableType> modelVisitor ) throws ThrowableType { constructorsModel.visitModel( modelVisitor ); // Compile error on this line } } public final class ConstructorsModel { public <ThrowableType extends Throwable> void visitModel( ModelVisitor<ThrowableType> modelVisitor ) throws ThrowableType { : } } The compile error is; /home/niclas/qi4j/qi4j-core/runtime/src/main/java/org/qi4j/runtime/composite/AbstractModifierModel.java:[75,36] unreported exception java.lang.Throwable; must be caught or declared to be thrown
Do you compile it with JDK 1.6 set to 1.5 compatibility level, or is installed JDK actually 1.5? And which OS?
I have JDK 1.6 (u20), which compiles that on 1.5 compatibility level (in Eclipse), on Win7 x64, and no compilation errors.
