Kevin A Shaw created AVRO-2682:
----------------------------------
Summary: Compiled schema cannot find symbol readFieldOrderIfDiff
(Java)
Key: AVRO-2682
URL: https://issues.apache.org/jira/browse/AVRO-2682
Project: Apache Avro
Issue Type: Bug
Components: java
Affects Versions: 1.9.1, 1.9.0, 1.10.0, 1.9.2
Environment: OS: MacOS 10.15.2
IDE: IntelliJ 2019.3.1 with Java9
Avro compiler: avro-tools 1.9.1
Libraries (via Maven): org.apache.avro:avro:1.9.1 and
org.apache.avro:avro-maven-plugin:1.9.1 (though several other versions have
been tested as well)
Reporter: Kevin A Shaw
Attachments: ActivityRecord2.avsc, ResolvingDecoder.java,
SpecificRecordBase.java, Test.java, Untitled.png
We are experimenting with Avro to generate data files for a large data repo we
are building.
Hence, we created a small test Avro Schema (see attached
`ActivityRecord2.avsc`). We compiled it with `avro-tools` using the following
command:
{{avro-tools compile schema ActivityRecord2.avsc ~/foobar/src/main/java}}
The resulting file, `Test.java` (attached) will not compile in IntelliJ with
Java9.
There are four messages (a screen shot of the source with highlighting is
attached: `Untitled.jpg`).
The errors are:
{code:java}
Error:(279, 3) java: method does not override or implement a method from a
supertype
Error:(281, 3) java: method does not override or implement a method from a
supertype
Error:(288, 3) java: method does not override or implement a method from a
supertype
Error:(291, 51) java: cannot find symbol
symbol: method readFieldOrderIfDiff()
location: variable in of type org.apache.avro.io.ResolvingDecoder
{code}
I have inspected the source for these to classes (ResolvingDecoder and
SpecificRecordBase), decompiled them from the Avro .jar library and stored the
resulting java source. These two files are attached and they definitely do not
have the required symbols present. These are from the 1.9.1 release.
I have used Maven to test several versions of the Jar Libraries (as listed
above), including Avro 1.8, 1.9 and 1.10, but with no improvements. I get the
same error for all of them.
Is there something that we are going wrong here?
