* @test
*
* @summary converted from VM Testbase nsk/jdi/ClassUnloadRequest/addClassFilter/filter001.
* VM Testbase keywords: [diehard, jpda, jdi, nonconcurrent]
* VM Testbase readme:
* DESCRIPTION:
* The test checks up the method
* com.sun.jdi.ClassUnloadRequest.addClassFilter(String)
* on the following assertion:
* Restricts the events generated by this request to the unloading
* of reference types whose name does not match a restricted regular
* expression.
* The cases to test include a pattern that begins with '*' and ends with '*'.
* The test works as follows:
* The debugger program - nsk.jdi.ClassUnloadRequest.addClassFilter.filter001;
* the debuggee program - nsk.jdi.ClassUnloadRequest.addClassFilter.filter001a.
* Using nsk.jdi.share classes, the debugger gets the debuggee running on
* another JavaVM and controls the classes loading/unloading on debugee.
* Each event is checked class name, which generates this event, to do
* match to defined filter.
* When class name does not match to defined filter, the test fails and
* produces a corresponding error message(s).
* Note: In case no events occured, test is considered as passed.
* COMMENTS:
* Fixed due to the bug 4677256
* The test was modified to comply with new execution scheme
* to have separate directory for precompiled classes:
* - all classes to be loaded by ClassUnloader were separated and
* moved into 'loadclass' subdirectory;
* - ${COMMON_CLASSES_LOCATION} instead of ${TESTDIR} in .cfg file;
* - ClassUnloader seekes for classes to load class in
* ${COMMON_CLASSES_LOCATION}/loadclass directory.
* Test updated to prevent possible VMDisconnectedException on VMDeathEvent:
* - throwing Failure exception on VMDisconnect is used in event handling loop
