Marco commented on DERBY-6175:
------------------------------
Hi again,
today, I encountered this bug for the first time *later* during an UPDATE
statement - i.e. not during the startup of my PMF - and therefore definitely
not related to DERBY-4160.
It occurs on my productive system, which totally sucks :-(
It happens pretty reproducible during a very long-running transaction, after
there was no DB activity for about 6 to 7 minutes: My code spends this time
reading a very large file and generating multiple SHA1 checksums (over the
entire file and its blocks).
Here's the relevant excerpt from the stack trace:
Caused by: javax.jdo.JDODataStoreException: Update of object
"co.codewizards.cloudstore.core.persistence.NormalFile@7045fc09" using
statement "UPDATE "repofile" SET "changed"=?,"lastmodified"=?,"sha1"=? WHERE
"id"=?" failed : java.sql.SQLNonTransientConnectionException: No current
connection.

Btw. I'm still using 10.10.1.1.
