Remove the jakarta-oro regex engine because:.

   - it is retired since 2010-09-01 [1] and the use of regex feature from java is encouraged [2].

   - Ant also considers that the Java's built-in regex package is likely the best choice going forward. [3]

   - Built-in regex package is available in Java since 1.4 (Feb 2002) [4].

This has been discussed in [5] and the consensus was to upgrade and simplify our framework.

According to my testing, the doc generated with the built-in parser or the oro parser are identical. (tested on Ubuntu 18.10, OpenJDK 1.8.0)
