* @test
*
* @summary converted from VM Testbase nsk/jvmti/ClassPrepare/classprep001.
* VM Testbase keywords: [quick, jpda, jvmti, noras]
* VM Testbase readme:
* DESCRIPTION
* The test exercises JVMTI event callback function ClassPrepare.
* The test checks if class prepare event is generated when
* class preparation is complete, and, at this point, class
* fields, methods, and implemented interfaces are available,
* and no code from the class has been executed.
* COMMENTS
* Fixed according to the bug 4651181.
* Ported from JVMDI.
*
* @requires vm.continuations
* @library /test/lib
* @compile --enable-preview -source ${jdk.version} classprep01.java
* @run main/othervm/native --enable-preview -agentlib:classprep01 classprep01
