Attila Doroszlai commented on RATIS-1946:
-----------------------------------------
It seems these {{Annotated\*Exception}} classes just wrap the underlying
exception, adding the remote address to the message. Their
{{fillInStackTrace()}} are no-ops.
> slf4j: Exception may not be printed.

> URL: https://issues.apache.org/jira/browse/RATIS-1946
> Project: Ratis
> Issue Type: Improvement
> Reporter: Tsz-wo Sze

> Time Spent: 10m
> Remaining Estimate: 0h

> The "{}" message format syntax does not work for exception.
> {code}
> //PeerProxyMap.java
> } catch (IOException e) {
> LOG.warn("{}: Failed to close proxy for peer {}, proxy class: {}",
> name, pp, proxy.getClass(), e);
> }
> {code}
> As an example, the exception e and its stack trace will not be printed in the
> code above since it is calling
> {code}
> //org.slf4j.Logger
> void warn(String var1, Object... var2);
> {code}
> with one "{}" less. There are three "{}" but four objects (including e).
> The expectation is to call
> {code}
> void warn(String var1, Object var2, Object var3, Object var4, Throwable
> var5);
> {code}
> but such method does not exist.
