-Xverify

As described in the Oracle documentation, this HotSpot option enables or disables the verifier. For compatibility, this option is also supported by the Eclipse OpenJ9™ VM.

Setting	Effect	Default
`-Xverify`	Enables verification for all non-bootstrap classes. `-Xfuture` verification is not enabled.	yes
`-Xverify:all`	Enables verification for all classes and enables `-Xfuture` verification. You cannot use this setting in conjunction with -XX:+ClassRelationshipVerifier. Note: This setting might have an impact on performance.
`-Xverify:remote`	For compatibility, this parameter is accepted, but is equivalent to the default `-Xverify`.
`-Xverify:none`	Disables the verifier. Note: This is not a supported configuration and, as noted, was deprecated from Java 13. If you encounter problems with the verifier turned off, remove this option and try to reproduce the problem.
