   ### What would you like to be improved?
   
   In core/src/main/java/org/apache/gravitino/lock/LockManager.java, the 
deadlock logging in LockManager attempts to format the entire map instead of 
the actual timestamp, leading to an IllegalArgumentException when checking for 
long-held locks.
   
   Here's a test to show this:
   ```
     @Test
     void testCheckDeadLockDoesNotThrow() {
       LockManager lockManager = new LockManager(getConfig());
       TreeLockNode node = new TreeLockNode("test-node");
       node.addHoldingThreadTimestamp(
           Thread.currentThread(),
           NameIdentifier.of("test"),
           System.currentTimeMillis() - TimeUnit.SECONDS.toMillis(40));
       Assertions.assertDoesNotThrow(() -> lockManager.checkDeadLock(node));
     }
   ```
   
   ### How should we improve?
   
   just format the timestamp
