* @test
*
* @summary converted from VM Testbase nsk/jdi/Event/equals/equals001.
* VM Testbase keywords: [quick, jpda, jdi]
* VM Testbase readme:
* DESCRIPTION:
* The test for public equals() method of an implementing class of
* com.sun.jdi.event.Event interface.
* The test checks an assertion cited from spec for equals() method of
* java.lang.Object class:
* The equals method implements an equivalence relation:
* - It is reflexive: for any reference value x, x.equals(x) should return true.
* - It is symmetric: for any reference values x and y, x.equals(y) should return
* true if and only if y.equals(x) returns true.
* - It is consistent: for any reference values x and y, multiple invocations
* of x.equals(y) consistently return true or consistently return false,
* provided no information used in equals comparisons on the object is modified.
* - For any non-null reference value x, x.equals(null) should return false.
* COMMENTS:
* The test is aimed to increase jdi source code coverage and checks
* the code which was not yet covered by previous tests for Event
* interface. The coverage analysis was done for jdk1.4.0-b92 build.
* Test updated to prevent possible VMDisconnectedException on VMDeathEvent:
* - resume for these events is skipped in event handling loop
* - method Debugee.endDebugee() is used instead of Debugee.waitFor()
* Test fixed according to test bug:
* 4854711 TEST_BUG: race condition in threads synchronization
