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:
https://github.com/zolyfarkas/avro/commit/762ccdc2aecd4cd8668a86562165e5babdce019b
> Java serialization readers/writers in generated Jaca classes

> Key: AVRO-1707
> URL: https://issues.apache.org/jira/browse/AVRO-1707
> Project: Avro
> Issue Type: Improvement
> Affects Versions: 1.8.0
> Reporter: Zoltan Farkas
>
> 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...
