This syntax is reserved to be likely used in the future as a shorthand for
"this::foo" where the resulting expression doesn't take the receiver as a
parameter but has "this" already bound to it
Each property reference obtained by the '::' operator now causes back-end to
generate an anonymous subclass of the corresponding KProperty class, with the
customized behavior. This fixes a number of issues:
- get/set/name of property references now works without kotlin-reflect.jar in
the classpath
- get/set/name methods are now overridden with statically-generated property
access instead of the default KPropertyImpl's behavior of using Java
reflection, which should be a lot faster
- references to private/protected properties now work without the need to set
'accessible' flag, because corresponding synthetic accessors are generated at
compile-time near the target property
#KT-6870 Fixed
#KT-6873 Fixed
#KT-7033 Fixed
- use ConcurrentHashMap as a cache of class loaders to module descriptors
- KClassImpl now has a lazy class descriptor and it manages property creation
by looking (also lazily) for the property descriptor in the corresponding
scope
- since deserialized descriptors have full information about where a JVM symbol
is located and what signature it has, new tests will begin to pass where
Kotlin model and Java reflection model differ, see classObjectVar.kt
The former name clashes with java.lang.IllegalAccessException and proved to be
inconvenient because it should always be qualified in the source.
Also use java.lang exception's message as kotlin.reflect exception's message
