After ugrade to latest master: temporay errors : class not found

[Björn Pedersen]

Hi,

after a recent upgrade to  a master build on a test machine I found the following in the javamelody logs
 
for each request like:

   /changes/?q=status:open+is:mergeable+conflicts:8&O=a GET

I get (once):

WARN [com.google.gerrit.server.cache.h2.H2CacheImpl] Cannot build BloomFilter for jdbc:h2:file:///home/gerrit/cache/conflicts: Deserialization failed, cause: "java.lang.ClassNotFoundException: com.google.gerrit.extensions.common.SubmitType" [90027-176]

After that everything seems to work normally, including the request in question if performed manually.

Is this an expected upgrade effect? Or should  the upgrade just  flush the caches?

I just upgrade to 2.12.2 and I see this :

[2016-07-15 20:11:12,336] [HTTP-239] WARN  com.google.gerrit.server.cache.h2.H2CacheImpl : Cannot build BloomFilter for jdbc:h2:file:///opt/nmtgre-tools/gerrit/cache/conflicts: Deserialization failed, cause: "java.lang.ClassNotFoundException: com.google.gerrit.extensions.common.SubmitType" [90027-176]

repeatedly.

Is it bad?  How do I resolve this?

Thank you

It looks like flushing the conflicts cache solved the problem, e.g. by ssh:

  ssh <user>@<host> -p <port> gerrit flush-caches --cache conflicts

by following this thread: https://groups.google.com/forum/#!topic/repo-discuss/iJQLUdWC19Y

Thanks
