Currently we have two JIRA issues classified as "Blockers": https://issues.apache.org/jira/browse/DERBY-3260
and https://issues.apache.org/jira/browse/DERBY-3303 DERBY-3260 has a patch which has been reviewed favorably by Knut, but I feel that the following quote from his comment deserves some attention: "It would be interesting, though, if someone could shed some light on why the synchronization was commented out in the first place. This piece of code hasn't been changed since the code was donated to Apache, so the commit log doesn't tell us anything about it." It seems like both DERBY-3303 and its "Critical" cousin DERBY-3231 are caused by rev 516454 (fix for DERBY-681), (a fix was checked in for DERBY-3231, but it remains open). Is there any chance of these being fixed in time for 10.4? -- dt
