A portable Java compiler from Eclipse (ecj) and decompiling capabilities (e.g. Procyon) are appropriately licensed and could be part of the startup.

  • JCasGen could be "automatic" for merged type systems, and merged instances of JCasGen'd user classes?
    • Users still would need a generated version for their code to compile against.
  • elimiated?Pear definitions for JCas cover classes could be merged?
  • Could generate one kind of Java cover class for all types. (lazy, load on demand
    • eliminate / reduce use of TypeImpl in runtime.
    • generate for all merged types (except custom built ins)
      • (as opposed to current impl, where no JCas cover class is generated if it doesn't exist - the "standard" one is used instead)
  • use class loader technology to support multiple type systems.
    • only for class definitions that have same name but are different.

...

  • To get around "reflection" slowness: 
    • Support set/get by int <- class <- feature-name-string
    • Support set/get (bulk) ? <ordering among fields significant?>

More concurrency

Support parallel running of pipeline components.

Careful trade-off vs slower due to synchronization, cache-line interference.  Key is to separate things being updated. 

Consider special index support for this
