Goldstein Lyor commented on SSHD-736:
-------------------------------------

Hi [~davido2],
In order to provide a solution or at least a workaround I need a few more details:
{quote}
It seems, that during start of FileSystem, it loads all file system providers on the classpath
{quote}

* Who is starting the file system - Java or your code ?
* If Java, how do you explain the fact that only your development environment is failing - is it trying to do something with the loaded file system providers ?
* If your code is starting the FileSystem what does "start" mean ? What is it trying to do ?

Any other light you can shed on it can help a lot - e.g., logs from the startup process, or whatever other information you deem relevant
Thanks,
Lyor

>             Project: MINA SSHD
>          Issue Type: Question
>    Affects Versions: 1.4.0
>         Environment: Linux, Gerrit
>            Reporter: David Ostrovsky
>            Assignee: Goldstein Lyor
>            Priority: Minor
>
> In the development environment, we are using java filesystem,
> to short circuit loading of servlets for the JavaScript Polymer UI.
> Since upgrade to 1.4.0 Gerrit refuses to start in such dev environment.
> I seems, that during start of FileSystem, it loads all file system providers
> on the classpath. Since sshd-core is on the lcasspath, it's trying to load
> also {{SftpFileSystemProvider}}, and is failing with class custom exception: [1].
> Note, that we don't do that when booting release gerrit version, so we
> do see this poblem only in the development environment.
> We have 2 work arounds so far: disable file system usage in gerrit in this
> code path: [2], or use custom built sshd-core version without this file[3]:
>    {{sshd-core/src/main/filtered-resources/META-INF/services/java.nio.file.spi.FileSystemProvider}}
