Vladimir Beliaev updated HARMONY-2052:
--------------------------------------
Attachment: antlr-2.7.5.jar
I've attached 'antlr-2.7.5.jar' file which is 'it is fully in the public domain' (according
to http://www.antlr2.org/license.html) because of this JAR is not available at www.antlr2.org
now...

> Improve/re-implement a parser of generic signatures in DRLVM kernel classes [1], and
move this functionality to classlib (luni ?), so other VMs could reuse it for 1.5 support.
The current impl is somewhat messy and half-baked, one need to invent more shaped and modular
API to the parser. One more possible issue is parser's dependency on antlr, which may be considered
overkill for this duty. I think antlr has its pros, like more illustrative code with clear
correlation to formal grammar [2]; unfortunately this is not the case with the impl in question.
OTOH minimizing number of dependencies for VM is always good.
