Will GC lose some locking infomation during compaction?

I have two questions about GC's compaction phase.
1. During the compaction, after GC copies a compacted object to the its
location, it always calls "init_mark" on this object. I think "init_mark"
will cause the object to be "unlocked". If the object is "locked" before
compaction, will the locking information be lost after compaction?
2. If the compacted object has enter a monitor (using "moniterenter"), GC
moves it to new location, then how can GC update the monitor?
Thanks a lot!
