>                 Key: AVRO-1592
>                 URL: https://issues.apache.org/jira/browse/AVRO-1592
>             Project: Avro
>          Issue Type: Bug
>          Components: java
>    Affects Versions: 1.7.7
>         Environment: CentOS, Java 1.7
>            Reporter: Lukas Steiblys

> The schema {"type": "enum", "name": "ButtonTypeID", "symbols": ["default", "keyboard"]} generates the following class:
>  
> public final class ButtonTypeID extends java.lang.Enum<ButtonTypeID> {
>   public static final ButtonTypeID default$;
>   public static final ButtonTypeID keyboard;
>   public static final org.apache.avro.Schema SCHEMA$;
>   public static ButtonTypeID[] values();
>   public static ButtonTypeID valueOf(java.lang.String);
>   public static org.apache.avro.Schema getClassSchema();
>   static {};
> }
>  
> (this is what “javap ButtonTypeID.class” produces)
>  
> When I try to read my data that has the “default” value for ButtonTypeID, I get the exception:
> java.lang.IllegalArgumentException: No enum constant ButtonTypeID.default
> 	at java.lang.Enum.valueOf(Enum.java:236)
> 	at org.apache.avro.specific.SpecificData.createEnum(SpecificData.java:106)
> 	at org.apache.avro.generic.GenericDatumReader.createEnum(GenericDatumReader.java:205)...
> Since "default" is a keyword in java, the $ is appended to the constant, but that is not taken into account when reading the data back, causing the ButtonTypeID.valueOf("default") method to fail.
