Description

Changes to JCasGen approach.

Allow users an easy migration from existing JCasGen classes

• a reporting tool that identifies existing JCas gen classes being used
• tooling support for setting up "merged" JCasGen class definitions from multiple sources
  • Goal: support PEARs having different (but mergable) JCasGen definitions

Internal: only one class per type - the xxx_type class is removed in UV3

• document migration path for users previously using xxx_type capabilities for low-level CAS operation

Document use-cases for JCasGen customization and changes possible due to new support for JavaObjects as data in Features.

Document the use-cases supported, including

• A single set of JCasGen classes used for different type systems
• External semi-manual merging of JCasGen classes from PEARs and their
  containers
• Continuing to have JCasGen optional
