Comment 2 Vladimir Kvashin 2012-12-07 08:38:12 UTC 
Snapshot shows that 3/4 time is in extremely deep recursive calls of two methods calling each other:
  MacroExpandedToken.getText
  APTMacroExpansion.getText
  MacroExpandedToken.getText
  APTMacroExpansion.getText
  ...
And about 18% is in 
  APTUtils.getExpandedToken which goes into a very deep recursion
