Allows stringent class-file format checks that enforce shut conformance to the class-file format specification. Developers should use this flag when building new code. Stricter checks may possibly develop into the default in long term releases.
Logging will also be controlled at operate time via Diagnostic Instructions (While using the jcmd utility). All the things which might be specified to the command line can also be specified dynamically Using the VM.
Also, a system that's been up for a long period could produce excessive fragmentation, which could ensure it is unattainable to reserve more than enough massive site memory. When this comes about, possibly the OS or JVM reverts to employing standard webpages.

Decreases the level of obtain Handle checks inside the verifier. By default, this feature is disabled, and it’s overlooked (that is, taken care of as disabled) for classes by using a current bytecode Model. It is possible to enable it for courses with older versions from the bytecode.
