These tests are designed to test the most basic functionality of URLClassLoader to ensure that the support exists and works.

25


26
Note here that "noTimestampChecks" stops the shared classes support from recognising that jar files have been updated

27


28
Sanity.BuildInitial

29
	Creates an A.jar in the test directory and an A_ext.jar in the test JRE extensions directory

30
	The data classes in this jar file print "CACHED" when they are run

31


32
Sanity.success

33
	Stores the classes in the cache from A.jar and A_Ext.jar by running A_Main

34
	A NoClassDefFoundError is likely to be an error with the jar extensions directory

35


36
Sanity.BuildVerify

37
	Builds a new A.jar and A_Ext.jar which print "LOCAL" when they are run

38
	The classes are in the VerifyClasses subdirectory

39


40
Sanity.verifySuccess

41
	Runs A_Main with "noTimestampChecks" which means that if the original "CACHED" classes are properly cached,

42
	they will be loaded and run. If the classes from the new jar files are loaded, "LOCAL" is printed, which is an error.

43


44
Sanity.verifyStale

45
	Runs A_Main without "noTimestampChecks". Expects that the JVM will spot that the jar file has changed and then

46
	even though the required classes are in the cache, it should load the new ones from disk instead.
