Hi,
I've been trying to use avro-tools to verify Avro implementations, and I've
come across an issue. Perhaps someone here might be able to help?
When I run avro-tools with some subcommands, it prints a bunch of warnings
(see below) to the standard output. Does anyone know a way to disable this?
I'm using openjdk 11.0.5 under Ubuntu 18.04 and avro-tools 1.9.1.
The warnings are somewhat annoying because they can corrupt output of tools
that print to the standard output, such as recodec.
Aside: is there any documentation for the commands in avro-tools? Some seem
to have some command-line help (though unfortunately there doesn't seem to
be a standard way of showing it), but often that help often doesn't
describe what the command actually does.
Here's the output that I see:
WARNING: An illegal reflective access operation has occurred
