--------------------------------------
This seems similar to JCLOUDS-1640 can you see if there is an equivalent fix?
> Exception listing S3 dir where path contains %

> Key: JCLOUDS-1475
> URL: https://issues.apache.org/jira/browse/JCLOUDS-1475
> Project: jclouds
> Issue Type: Bug
> Components: jclouds-blobstore
> Affects Versions: 2.1.1
> Environment: MacBook Pro, OSX High Sierra (10.13.6)
> Reporter: Dave Bradlee
> Priority: Major
> Labels: s3
>
> Issue 278 was a similar problem, seemingly pretty different code path.
> Doing S3BlobStore.list, if directory name is something like Baz%, an
> exception is thrown. Encoding the % avoids the exception, but does not find
> the directory to return results. Interestingly, %Baz works. I believe the
> problem is that http.utils.Queries.parseQueryToDecodedMap decodes the entire
> path string, when it really only cases about the parameters. I think %Baz
> works because %Ba is a valid escape pattern. So it gets put in the parameter
> map, but never used.
> Here's a call stack. My path within an S3 bucket is "dgb6/Foo/Baz%" .
