Allon Mureinik has submitted this change and it was merged. Change subject: core: Fix double checking ...................................................................... core: Fix double checking These getInstance() methods implement a double-checking scheme to initialize the instance static member. In order for this mechanism to operate correctly, the instance member should be defined as volatile (see, e.g., http://www.cs.umd.edu/~pugh/java/memoryModel/DoubleCheckedLocking.html).
