[jira] Commented: (DERBY-3658) LOBStateTracker should not use
SYSIBM.CLOBRELEASELOCATOR when the database is soft-upgraded from 10.2
[ https://issues.apache.org/jira/browse/DERBY-3658?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12593786#action_12593786 ]
Kristian Waagan commented on DERBY-3658:
----------------------------------------
The approach taken seems sound. +1 to commit if the tests pass.
I missed the point when I implemented this, believing if the server supported locators Cursor.locator would return a valid locator.
Does it make sense to explicitly note the possibility of an invalid locator even if the server supports it, for instance in [Net]Cursor.locator?
That said, the possibility of getting INVALID_LOCATOR should of course have made me check the value...
