Build Identifier: 20110916-0149

I have two projects.
Project A imports some jars j.jar and k.jar.
Nothing but project A's source is exported under "Order and Export".
Project B imports project A.
The following command executed from within B, which is run through a launch configuration:
System.err.println( System.getProperty( "java.class.path" ) );
includes j.jar and k.jar from project A.

Reproducible: Always

This is in the "Java Build Path" preferences, right?
So the effect is, that the compiler will not let a project importing A refer to classes from j.jar or k.jar. These checks happen at compile time.

This, in contrast, happens at runtime. Now for classes in A to correctly be loaded and their code executed they'll likely depend on j.jar and k.jar. So without those jars on the classpath, A would be broken.

Please let me know if I misunderstood anything.
Otherwise I'd say everything works exactly as intended.

Ok, I think, you opened my eyes. Thanks. Should be alright then.
