Class ThreadAwareSecurityManager

  • public final class ThreadAwareSecurityManager
extends java.lang.SecurityManager
    Custom SecurityManager and Policy implementation that only performs access checks if explicitly enabled.

    This implementation gives no measurable performance penalty (see see cstar test). This is better than the penalty of 1 to 3 percent using a standard SecurityManager with an allow all policy.
