Steps to Reproduce

1. Start up Liferay connected to a MySQL database
2. Sign in as admin
3. Navigate to Control Panel > Configuration > Server Administration
4. Go to the Script tab
5. Run the following Groovy script:

   import com.liferay.asset.kernel.service.AssetVocabularyLocalServiceUtil;
   import com.liferay.asset.kernel.service.AssetCategoryLocalServiceUtil;
   import com.liferay.portal.kernel.model.GroupConstants
   import com.liferay.portal.kernel.service.GroupLocalServiceUtil
   import com.liferay.portal.kernel.service.ServiceContext;
   import com.liferay.portal.kernel.util.PortalUtil
   import com.liferay.portal.kernel.util.StringUtil
   
   import java.util.concurrent.Executors;
   
   userId = PortalUtil.getUserId(actionRequest);
   companyId = PortalUtil.getCompanyId(actionRequest);
   groupId = GroupLocalServiceUtil.getGroup(companyId, GroupConstants.GUEST).getGroupId()
   
   serviceContext = new ServiceContext()
   
   vocabularyName = "Groovy_TestVocabulary"
   vocabulary = AssetVocabularyLocalServiceUtil.fetchGroupVocabulary(groupId, "Groovy_TestVocabulary")
   
   if (vocabulary == null) {
       vocabulary = AssetVocabularyLocalServiceUtil.addVocabulary(userId, groupId, vocabularyName, serviceContext);
   }
   
   threadPool = Executors.newFixedThreadPool(3)
   
   (1..10).each {
       threadPool.execute {
           AssetCategoryLocalServiceUtil.addCategory(userId, groupId, "cat-" + StringUtil.randomString(5) + "-" + StringUtil.randomId(5), vocabulary.getVocabularyId(), serviceContext);
       }
   }
   
   threadPool.shutdown()

6. Inspect the AssetCategory table in the database
7. Check the various rows in the AssetCategory table, and assert that some rows are showing duplicate leftCategoryId and rightCategoryId as the previous entry.

Actual Behavior
Rows are showing duplicate leftCategoryId and rightCategoryId in multiple rows.

Expected Behavior
Rows should have unique leftCategoryId and rightCategoryIds.
