There are empty entries (marked TBD for "to be defined") because we think of things that we need to define faster than we think of good definitions. adaptive spinning An optimization technique whereby a thread spins waiting for a change-of-state to occur (typicall

Compressed oops in the Hotspot JVM What's an oop, and why should they be compressed? An "oop", or "ordinary object pointer" in HotSpot parlance is a managed pointer to an object. It is normally the same size as a native machine pointer, which means 64 bits on an LP64 system. On an ILP32 system, there is a maximum heap size of somewhat less than 4Gb, which is not enough for many applications. On an
