This analysis reports the specified security properties of the used JVM.
This analysis reports the specified security properties of the used JVM. We are in particular interested
in the information about the restricted packages. These information can only be leveraged if the security manager
is set before starting the program. Setting the SecurityManager in the program's main function is to late since a lot
of classes has been load already.
The package.definition property is by default not checked by any class loader. Hence, it is not safe to leverage this
information.
There are two kinds of packages where a "java.lang.SecurityException" is thrown.
1. packages with access restrictions: (package.access property)
List of comma-separated packages that start with or equal this string
will cause a security exception to be thrown when
passed to checkPackageAccess unless the
corresponding RuntimePermission ("accessClassInPackage."+package) has
been granted.
2. packages with (package.definition property)
List of comma-separated packages that start with or equal this string
will cause a security exception to be thrown when
passed to checkPackageDefinition unless the
corresponding RuntimePermission ("defineClassInPackage."+package) has
been granted.
by default, none of the class loaders supplied with the JDK call
checkPackageDefinition.
Commandline Arguments:
-conf | shows the current (merged) opal configuration
