[jira] [Commented] (AVRO-1055) Race condition in Java fingerprinting code

    [ https://issues.apache.org/jira/browse/AVRO-1055?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13250094#comment-13250094 ] 

Doug Cutting commented on AVRO-1055:
------------------------------------

+1 Looks good to me.  You might add a comment saying something like, "Nested class used so that table is not built unless it's used."

> There is a subtle race condition. If the fpTable64 is not yet initialized and two thread try to compute FP for two schemas (or the same schema) at the same time, one thread will start initializing the table while the other can start using the partially initialized table giving wrong result.
> The forthcoming patch fixes that issue
