[jdt-core-dev] Fix pass 1 update

[Philippe_Mulet@xxxxxxx]

During this 1st fix pass, we have addressed so far the following items:

- make the JDTCompiler Ant adapter compatible with Ant 1.5
- provide an API to allow refreshing explicitly external JARs
- provide an API to retrieve cached flags for type hierarchies
(performance)
- improved the line number debug attributes around the implicit free return
bytecode
- fix a bug in code gen leading to a verification error at runtime
- fix NullPointerException in compiler if it needs to filter out numerous
problems
- fix search when match is in internal jar of a distinct project
- fix a potential concurrency problem when creating the JavaModel element
- solve a couple rare scenarii where the incremental compiler would be
inconsistent
- register Team recommandations for certain file types (.java, .classpath,
.class, .jar, .zip, .properties)
- fix couple cases where local history wouldn't reflect JavaModel operation
(deletions)
- fix open on selection for instanceof expressions
- fix couple cases where platform encoding used in place of Eclipse custom
encoding (if any)

The corresponding sources have been tagged with the STABLE sticky tag, and
released for integration in build 20020529.
