X10Builder collecting bookmarks, need adjuncts

Polyglot nodes ... need adjunct nodes to fix this, hasn't been investigated yet. Adding this bug to take out the error log notification (too scary)

JPGPosition.getLeftIToken() problem (always null now, need general method to recompute)

!MESSAGE Error while collecting bookmarks during build: JPGPosition / adjuncts
!STACK 0
