Martin Tzvetanov Grigorov updated AVRO-3698:
--------------------------------------------
Description:
[Java] SpecificData.getClassName must replace reserved words
When makes Java Class, SpecificCompiler adds "$" after reserved words like
public, new, etc...
[https://github.com/apache/avro/blob/master/lang/java/compiler/src/main/java/org/apache/avro/compiler/specific/SpecificCompiler.java#L1129]
[https://github.com/apache/avro/blob/master/lang/java/compiler/src/main/java/org/apache/avro/compiler/specific/SpecificCompiler.java#L643]
For example, if the namespace of a schema is {*}db.public.table{*}, then the
package name of the generated Java Class, made by SpecificCompiler, is
{*}db.public$.table{*}. (Because *public* is a reserved word in java)
But when deserializes an Avro Record to a SpecificRecord,
SpecificData.getClassName returns {*}db.public.table.Name{*}.
So, it can't find a class by name from SpecificData.getClassName.
