Incrementally reduces the Java heap towards the concentrate on dimension, specified by the option —XX:MaxHeapFreeRatio. This feature is enabled by default. If disabled, then it right away cuts down the Java heap for the focus on dimension in lieu of requiring various garbage assortment cycles.

Decreases the level of obtain Handle checks from the verifier. By default, this option is disabled, and it’s dismissed (that is, addressed as disabled) for lessons using a new bytecode version. You can permit it for lessons with more mature variations in the bytecode.
