---------------------------------
Summary: Java keyword as an enum constant in schema file causes
deserialization to fail. (was: Appended dollar sign at the end of an enum
constant causes deserialization to fail.)
> Java keyword as an enum constant in schema file causes deserialization to
> fail.
> -------------------------------------------------------------------------------
>
> 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
> Attachments: avrobug.tar.gz
>
>
> 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.
