Method constructObject

src/bsh/Reflect.java:544–577

Primary object constructor This method is simpler than those that must resolve general method invocation because constructors are not inherited. This method determines whether to attempt to use non-public constructors based on Capabilities.haveAccessibility() and will set the accessibilty flag
