Metacat

do not wait for SM generation to complete during the upgrade -- this way the web UI wont hang for days. the process sets a metacat property when it is complete.

do not shutdown hazelcast -- it needs to be running after the upgrade process so that Metacat actually works.
I think the newer version of HZ makes it so the threads are all released as needed.

Commenting out the parts of the upgrade script that started to refer to EXID. At this point, the registration of EZID identifiers will be done out-of-band with respect to the upgrade.

upgrade to hazelcast 1.9.4.6 so that threadpools are released when not needed (http://code.google.com/p/hazelcast/issues/detail?id=765).
include ant target to run a specific main class (mostly for debugging)

multithreaded implementation for processing docids for system metadata generation.
need to investigate ant/junit running that deadlocks hazelcast (config?)

only attempt to update date-like nodedata values.

include generate system metadata upgrade in the success flag

more clean up - reuse prepared statement for data update

look up nodedata values first, then update each one - trying to avoid out of memory exception.
