Re: Java 1.4 support libraries (was [VOTE] Target Java 5, support
1.4
Retrotranslator replaces "extends java.lang.Annotation" with "extends net.sf.retrotranslator.runtime.java.lang.Annotation_", "java.lang.Class.getAnnotation" with "net.sf.retrotranslator.runtime.java.lang._Class.getAnnotation", and so on.
So application developers do not have to be aware of Retrotranslator:
http://cvs.sourceforge.net/viewcvs.py/retrotranslator/Retrotranslator/test/net/sf/retrotranslator/runtime/java/lang/_ClassTestCase.java?view=markup
The only drawback here is that translated code may be incompatible with libraries using Java 5 API directly (mainly because annotations do not extend java.lang.Annotation after translation). So you would have to distribute separate jars for 1.4 and 5.0 platform.

Annotations can be read at runtime only if accessing code and annotations are both translated with Retrotranslator.

Interesting, separate jars were always in the plan, so that isn't a problem. So you are saying the code can still
access the annotations at runtime?
