IcedTea6 contains:

HS_MAJOR_VER=10
HS_MINOR_VER=0
HS_BUILD_NUMBER=19

IcedTea/b33 contains:

HS_MAJOR_VER=14
HS_MINOR_VER=0
HS_BUILD_NUMBER=01

icedtea-hotspot-6b11-7b24.patch only updates the src code and not
make/hotspot_version
so it's actually worryingly building a different version of HotSpot
from the one it thinks it is.
It will actually be 12-0-01 as you state, but will report 10-0-19.

Overall, it would be better to always build against the most recent
stable HotSpot tree if possible
rather than the one provided by the build drop.  Do we know what the
most stable would be?
