| * VM Testbase readme: |
| * DESCRIPTION |
| * Debuggee VM create thread which acquires 5 different monitors in following ways: |
| * - entering synchronized method |
| * - entering synchronized method for thread object itself |
| * - entering synchronized static method |
| * - entering synchronized method for thread class itself |
| * - entering synchronized block on non-static object |
| * Information about all monitors acquired by test thread is stored in debuggee VM and can be obtained through |
| * special field in debuggee class: OwnedMonitorsDebuggee.monitorsInfo. |
| * Debugger VM reads information about acquired monitors from 'OwnedMonitorsDebuggee.monitorsInfo' |
| * and checks that com.sun.jdi.ThreadReference.ownedMonitorsAndFrames returns correct list of MonitorInfo objects. |
| * Debugger VM forces test thread in debuggee VM sequentially free monitors through Object.wait(), |
| * updates debug information about acquired monitors and checks that com.sun.jdi.ThreadReference.ownedMonitorsAndFrames |
| * returns correct list of MonitorInfo objects. |
| * Debugger VM forces test thread in debuggee VM free all monitors(exit from all synchronized objects/blocks), |
| * update debug information about acquired monitors and checks that com.sun.jdi.ThreadReference.ownedMonitorsAndFrames |
| * returns correct list of MonitorInfo objects. |
