Spring allows to you, to fall-back on system properties, if you not added any corresponding values with that.
That is really a cool feature. If you need to look up,some system properties , you don’t need to do any thing
just configure your bean and Spring will take care that.
These are the some of SYSTEM_PROPTTIRES that you set in your bean
SYSTEM_PROPERTIES_MODE_FALLBACK Check system properties if not resolvable in the specified properties.
SYSTEM_PROPERTIES_MODE_NEVER Never check system properties.
SYSTEM_PROPERTIES_MODE_OVERRIDE Check system properties first, before trying the specified properties.

Lot of times your eclipse get crashed while working, because of out of memory. I would suggest to increase your memory in-case your project is huge and keep on crashing.
You can increase vm size of eclipse by changing eclipse.ini. There are memory argument for vm
“-vmargs -Xms40m -Xmx256m”
Even on increasing the memory, eclipse is crashing check the log, as lot of time installed plugins, lead of eclipse crashing.
