                                       IllegalArgumentException
Query the property with the name propertyKey.

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.

Parameters:
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.
Returns:
the property value if exists, or null
Throws:
NullPointerException - if the property name is null
IllegalArgumentException - if the property name is of length 0
SecurityException - if access is not allowed to the given propertyKey
