Subject [jira] [Updated] (AVRO-1047) Generated Java classes for specific records contain unchecked casts
Date Wed, 14 Nov 2012 23:50:12 GMT

     [ https://issues.apache.org/jira/browse/AVRO-1047?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Garrett Wu updated AVRO-1047:
-----------------------------

    Attachment: suppress-warnings.tar.gz

I'm using Oracle Java 1.6.0_31.

I've attached a small example to demonstrate the @SuppressWarnings("all") seems to have no
effect for me.

{code}
$ javac -version
javac 1.6.0_31

$ javac Foo.java # Using @SuppressWarnings("all")
Note: Foo.java uses unchecked or unsafe operations.
Note: Recompile with -Xlint:unchecked for details.

$ javac Bar.java # Using @SuppressWarnings("unchecked")
{code}

> The generated Java classes for specific records cause compiler warnings using Oracle/Sun
Java 1.6, since it doesn't support @SuppressWarnings("all"). Instead could we change it to
@SuppressWarnings("unchecked")? Only "unchecked" and "deprecation" are mentioned Java Language
Specification -- the rest are specific to compiler vendors.
