| * @test |
| * |
| * @summary converted from VM Testbase nsk/monitoring/CompilationMXBean/comptimemon001. |
| * VM Testbase keywords: [quick, monitoring] |
| * VM Testbase readme: |
| * DESCRIPTION |
| * The test checks that |
| * CompilationMBean.isCompilationTimeMonitoringSupported() |
| * method returns true. The test performs directly access to management |
| * metrics within the same JVM. |
| * Note, that the test is correct ONLY against Sun's Hotspot VM. This |
| * feature is optional and the method may return either true, or false. |
| * However, Sun's implementation must always return true. |
| * The test passes, if the JVM has no compilation system, for example the |
| * test is invoked with -Xint option. |
| * COMMENT |
| * Fixed the bug: |
| * 4953476 TEST_BUG: The spec is updated accoring to 4944573 and 4947536 |
| * |
