Modifier and Type	Method and Description
`abstract void`	`doRelockObject(Object obj, Object lockData)`
`protected abstract void`	`doWait(Object obj, long timeoutMillis)`
`abstract boolean`	`isLockedByAnyThread(Object obj)` Determines whether the object's monitor is locked by the current or any other thread.
`abstract boolean`	`isLockedByCurrentThread(Object obj)` Implements the semantics of `Thread.holdsLock(java.lang.Object)`.
`abstract int`	`maybeAdjustNewParkStatus(int status)` Called from `Unsafe.park` when changing the current thread's state before parking the thread.

`void`	`wait(Object obj, long timeoutMillis)` Implements the semantics of `Object.wait(long)`.

public static MonitorSupport singleton()

monitorEnter
```
public abstract void monitorEnter(Object obj)
```
Implements the semantics of the monitorenter bytecode.

monitorExit
```
public abstract void monitorExit(Object obj)
```
Implements the semantics of the monitorexit bytecode.

public abstract Object prepareRelockObject(Object obj)

public abstract void doRelockObject(Object obj,
                                    Object lockData)

isLockedByCurrentThread
```
public abstract boolean isLockedByCurrentThread(Object obj)
```
Implements the semantics of Thread.holdsLock(java.lang.Object).

isLockedByAnyThread
```
public abstract boolean isLockedByAnyThread(Object obj)
```
Determines whether the object's monitor is locked by the current or any other thread.

public final void wait(Object obj,
                       long timeoutMillis)
                throws InterruptedException

Implements the semantics of Object.wait(long).

protected abstract void doWait(Object obj,
                               long timeoutMillis)
                        throws InterruptedException

public abstract void notify(Object obj,
                            boolean notifyAll)

Implements the semantics of Object.notify() and Object.notifyAll().

maybeAdjustNewParkStatus
```
public abstract int maybeAdjustNewParkStatus(int status)
```
Called from Unsafe.park when changing the current thread's state before parking the thread. When the thread is parked due to a monitor operation, we need to alter the new thread state so Thread.getState() gives the expected result.
