.
If jnlpAlias
is true
and the plain propertyKey
could not be resolved, an attempt to resolve the JNLP aliased trusted property is made.
Example: For the propertyName OneTwo
, the jnlp alias name is jnlp.OneTwo
, which is considered trusted.
propertyKey
- the property name to query.jnlpAlias
- true if a fallback attempt to query the JNLP aliased trusted property shall be made,
otherwise false.acc
- the AccessControlerContext to be used for privileged access to the system property, or null.NullPointerException
- if the property name is nullIllegalArgumentException
- if the property name is of length 0SecurityException
- if access is not allowed to the given propertyKey
