  * Automatic descriptor generation requires attention to a few things.
  * <ul>
- * <li>A Java 6 or later Java compiler is required, and at least the
- * <code>pljava-api</code> jar must be on its class path. (The full

- * is required.) The jar must be on the class path in any case in order to

+ * PL/Java's API anyway, in which case the jar would already have to be on
+ * the class path.)
  * <li>When recompiling after changing only a few sources, it is possible the
  * Java compiler will only process a subset of the source files containing
  * annotations. If so, it may generate an incomplete deployment descriptor,
