| * VM Testbase readme: |
| * DESCRIPTION |
| * The test checks that a result of the method com.sun.jdi.forceEarlyReturn(Value value) |
| * complies with its specification. The test checks: |
| * - after force return occurred any locks acquired by calling the called method(if it is a synchronized method) |
| * and locks acquired by entering synchronized blocks within the called method are released in Debuggee VM. |
| * Also checks that this does not apply to JNI locks or java.util.concurrent.locks locks. |
| * - MethodExitEvent is generated as it would be in a normal return |
| * Test scenario: |
| * Special thread class 'TestThread' is used in debugee VM. This class contains following test method: |
| * - it is synchronized method |
| * - JNI lock is acquired in this method |
| * - java.util.concurrent.locks.ReentrantLock is acquired in this method |
| * - at the end the method contains synchronized block |
| * Debugger initialize breakpoint in test method(inside the synchronized block) and force debugee VM run test |
| * thread which call this method. When debuggee's test thread stop at breakpoint debugger call forceEarlyReturn() |
| * and resume debuggee VM. |
| * Debugee's test thread after force return check that locks acquired through synchronized method and synchronized block |
| * was freed and JNI lock and java.util.concurrent.locks.ReentrantLock still locked. |
| * Also debugger checks that MethodExitEvent is generated after forceEarlyReturn. |
