|
* class loader module class
|
|
* -----------------------------------------------------
|
|
* boot java.base java/net/HttpCookie
|
|
* platform jdk.dynalink jdk/dynalink/DynamicLinker

* app jdk.compiler com/sun/tools/javac/Main

|
|
* This test dumps the above 3 classes into a shared archive.
|
|
* Then it will run the following 4 -limit-modules scenarios:
|
|
* 1. without --limit-modules
|
|
* All 3 classes should be loaded successfully.
|
|
* All 3 classes should be loaded by the appropriate class loader.
|
|
* All 3 classes should be found in the shared archive.
|
|
* 2. --limit-modules java.base,jdk.dynalink
|
|
* The loading of the com/sun/tools/javac/Main class should fail.
|
|
* The other 2 classes should be loaded successfully and by the appropriate class loader.
|
|
* The other 2 classes should be found in the shared archive.
|
|
* 3. --limit-modules java.base,jdk.compiler
|
|
* The loading of the jdk/nio/dynalink/DynamicLinker class should fail.
|
|
* The other 2 classes should be loaded successfully and by the appropriate class loader.
|
|
* The other 2 classes should be found in the shared archive.
|
|
* 4. --limit-modules jdk.dynalink,jdk.compiler
|
|
* The java.base module can't be excluded.
|
|
* The results for this case is the same as for case #1.
