Subject [jira] [Commented] (DERBY-5850) store/rollForwardRecovery fails with java.lang.ArrayIndexOutOfBoundsException
Date Mon, 09 Jul 2012 14:16:36 GMT

    [ https://issues.apache.org/jira/browse/DERBY-5850?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13409502#comment-13409502
] 

Knut Anders Hatlen commented on DERBY-5850:
-------------------------------------------

The ArrayIndexOutOfBoundsException looks like a JVM bug, as Character.isLetterOrDigit(char)
should never throw that exception.

However, the failing call to StringUtil.hexDump() happens in an error handler in CachedPage.changeInstanceTo(),
so the ArrayIndexOutOfBoundsException hides a StandardException that may be a problem in Derby:

        catch (StandardException se) 
        {
            if (se.getSeverity() > ExceptionSeverity.STATEMENT_SEVERITY)
            {
                throw se;
            }
            else
            {
                throw StandardException.newException(
                    SQLState.DATA_UNKNOWN_PAGE_FORMAT_2, 
                    newIdentity,
                    org.apache.derby.iapi.util.StringUtil.hexDump(pageData));
            }
		}
