java - Springsource ToolSuite won't load after attempting to create database connection in Database Development Perspective -

i added database development perspective , tried create first oracle database connection. got warning/error being low on memory, , read particular readme.txt file. didn't note down name, because assumed close/reopen application suffice.

now, sts won't load @ all. here's contents of .metadata/.log file. removed of stacktrace details fit under size requirement here.

i got invalid registry object when merely attempting select oracle driver. there way reset log or setting. i'm not looking forward creating new workspace , that entails. it's more little disapointing walking through wizard turns workspace toast.
