> Issue Type: Bug
> Affects Versions: 1.10.1, 1.12.1
> Reporter: JohnMTu
> Priority: Major
> Attachments: AvroIssueTest.java

> when having schema containing enum with enum-values like "new", "boolean", "null" which are java reserved keyword, then enum-value is generated with $ suffix using avro-maven-plugin.
> When i later try to serialize it to json, it fails on NPE.
> Normally i have similar enum deep in structure, and avro-maven-plugin is used. For simplicity of testcase, i copied generated class into test itself and instead of using massive structure i reproduce the problem when serializing enum itself.
> See attached test case. This is log output:
> {code:java}
> java.lang.NullPointerException: null value for (non-nullable) RecurringChargePeriod at org.apache.avro.path.TracingNullPointException.summarize(TracingNullPointException.java:88)
