-----------------------------------
[~katoquro] Do you have any code that we could compile/run where we could
replicate those stack traces?
> Using Closure (Groovy Construction like []) triggers loading of all

> URL: https://issues.apache.org/jira/browse/GROOVY-9646
> Project: Groovy
> Issue Type: Bug
> Affects Versions: 3.0.4
> Reporter: Andrew Malyhin
> Priority: Major
>
> After migration from Groovy 2.5.10 and jdk8 to Groovy 3.0.4 and jdk 11 we
> have faced the issue: the first using of closure inits FileSystemProviders
> from classpath which are not required:
> There are two traces that show initializing of
> org.apache.sshd.common.file.root.RootedFileSystemProvider just calling
