[stringtemplate-interest] it's 60% of time in ObjectModelAdaptor.getProperty()

[Terence Parr]

great info. i remember you told me a while back.

i wonder how easy this is in java using ASM or whatever.  i'd have to generate stubs and then figure out how to load. it's a solved problem but i wonder if there is a simple example.
