[jira] [Commented] (AVRO-1707) Java serialization readers/writers in generated Jaca classes

["Zoltan Farkas (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/AVRO-1707?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14634135#comment-14634135 ] 

Zoltan Farkas commented on AVRO-1707:
-------------------------------------

I propose:

1) Making this reference to the creator thread a SoftReference, this way we do not hold onto this thread instance past its expiration date...
2) make these readers/writers which are only used for java serialization Lazy, this way users who do not use java serialization do not pay the class loading penalty to initialize this reader/writer pair...

implementation:

> the following static instances are declared in the generated classes:
>   private static final org.apache.avro.io.DatumWriter
>     WRITER$ = new org.apache.avro.specific.SpecificDatumWriter(SCHEMA$);  
>   private static final org.apache.avro.io.DatumReader
>     READER$ = new org.apache.avro.specific.SpecificDatumReader(SCHEMA$);  
>  the reaser/writer hold on to a reference to the "Creator Thread":
> "private final Thread creator;"
> which inhibits GC-ing thread locals... for this thread...
