Vladimir Beliaev updated HARMONY-2052:
--------------------------------------

    Attachment: HARMONY-2052-1.diff

I've rebased HARMONY-2052-1.diff on recent Harmoby version, passed 'kernel tests' (which includes Generic tests & reflection test) on Windows/IA32 debug build default EM mode.

Alexey, please get this patch committed to simplify moving forward with this JIRA fixing.

Thanks
Vladimir Beliaev

> 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.
