Use this option to enable or disable the verifier.

With no parameters, enables the verifier, which is the default. Therefore, if used on its own with no parameters, for example, -Xverify, this option does nothing. Optional parameters are as follows:
  • all - enable maximum verification
  • none - disable the verifier
  • remote - enables strict class-loading checks on remotely loaded classes
The verifier is on by default and must be enabled for all production servers. Running with the verifier off is not a supported configuration. If you encounter problems and the verifier was turned off using -Xverify:none, remove this option and try to reproduce the problem.
