Field Detail

PATCHED_VERIFIED_ENTRY_POINT_INSTRUCTION_SIZE

public static final int PATCHED_VERIFIED_ENTRY_POINT_INSTRUCTION_SIZE

The size of the instruction used to patch the verified entry point of an nmethod when the nmethod is made non-entrant or a zombie (e.g. during deopt or class unloading). The first instruction emitted at an nmethod's verified entry point must be at least this length to ensure mt-safe patching.
