java.security.debug System PropertyThis system property controls whether the security system of the Java Runtime Environment (JRE) prints trace messages during execution. This option can be useful when diagnosing an issue involving a security manager when a SecurityException is thrown.
The java.security.debug property can have the following values:
access
Print all checkPermission results.
The following additional options can be specified with the access option:
stack
Include stack trace.
domain
Dump all domains in context.
failure
Before throwing an exception, dump the stack and domain that did not have permission.
jar
Print JAR verification information.
policy
Print permissions that SecureClassLoader assigns.
scl
For example, to print all checkPermission results and trace all domains in context, set the java.security.debug property to access,stack. To trace access failures, set the property to access,failure.
Example C-1 shows the output of a checkPermission failure.
Example C-1 Program for checkPermission Failure
