Thanks for the corrected evaluation. Just for your awareness, the HotSpot team is working on offering a spectrum of AOT/JIT options under the Leyden project [1]. Currently one has to choose between either a fully open world (JIT) or closed world (AOT) evaluation. The mixed world allows for a tunable knob, e.g. pre-warmup by AOT while retaining dynamic class loading and fast compile times for the application. This will soften the hard edges so developers can choose their constraints that best fit their application's deployment/usage model.
That is just a normal JVM with optional Graal components if enabled, but not being used. The default memory allocation is based on a percentage of available memory and uncommitted (meaning its available for other programs). When people mention Graal they mean an AOT compiled executable that can be run without a JVM installed. Sometimes they may refer to Graal JIT as a replacement for C1/C2 available also in VM mode. You are using a plain HotSpot VM in server mode, as the optimized client mode was removed when desktop use-cases were deprioritized (e.g. JWS discontinued).
