URL: https://github.com/apache/beam/pull/12907#issuecomment-698588738
Looks like someone made an SLF4J plugin for errorprone:
https://github.com/KengoTODA/errorprone-slf4j
I've gotten it hooked up so now I'll see about fixing all the errors (there
are others besides just the placeholder thing).

> Project: Beam
> Issue Type: Bug

> Reporter: Kyle Weaver
> Priority: P2
> Time Spent: 50m
> Remaining Estimate: 0h
>
> slf4j Logger has overloaded methods for each severity level:
> public void warn(String format, Object... arguments);
> public void warn(String msg, Throwable t);
> These two signatures are often confused:
> LOG.warn("foo {}", new Exception("bar"));
> This example does not print "foo bar" or anything like one would expect.
> Instead, "foo {}" (without any substitution). This often confuses Dataflow
> users.
> This pattern can be statically checked in Intellij. We should figure out how
> to enable similar checks using our existing static analysis tooling (perhaps
> errorprone?)
