[Bug report] Java GVFS client does not support Basic authentication #13685

Version

main branch (source inspected at 73f2ddd)

Describe what's wrong

The Java GVFS client only accepts simple, oauth2, and kerberos. Setting fs.gravitino.client.authType=basic throws an exception before sending a request.

The Java SDK and Python GVFS already support Basic authentication. This gap prevents Java GVFS from connecting to a Gravitino server configured with the built-in local user store and Basic authentication.

Expected behavior: Java GVFS supports basic with a username and password, consistent with the Java SDK and Python GVFS.

Error message and/or stacktrace

IllegalArgumentException: Unsupported authentication type: basic for fs.gravitino.client.authType.

How to reproduce

The following call reaches the unsupported-authentication branch in the current source:

Configuration conf = new Configuration();
conf.set("fs.gravitino.server.uri", "http://localhost:8090");
conf.set("fs.gravitino.client.metalake", "test_metalake");
conf.set("fs.gravitino.client.authType", "basic");
GravitinoVirtualFileSystemUtils.createClient(conf);

Additional context

• Java GVFS authentication selection
• Basic authentication was added in [#10959] feat(idp-basic): Add Basic authentication for built-in IdP #11226; the existing Java SDK withBasicAuth(username, password) can be reused.
