Simple Java Mail 9.1.6 is a patch release for applications using the Spring module.

• spring-module no longer packages its test application.properties. In versions 9.0.0 through 9.1.5, those sample values could override an application's YAML settings; the local-bind test value 192.0.2.30:25259 could then prevent SMTP connections.
• A packaging guard now prevents root application.* and bootstrap.* configuration files from entering the production artifact.

No public API changed, and Java 8 compatibility is retained. If you use spring-module 9.0.0 through 9.1.5, upgrade to 9.1.6 or later. After upgrading, the withLocalBindAddress("0.0.0.0", 0) workaround is no longer needed.

See #681.

Simple Java Mail 9.1.5 is a patch release fixing SOCKS5 domain framing in authenticated SOCKS support.

• Domain connect requests now place the two-byte port after the UTF-8-encoded hostname bytes, fixing malformed requests for internationalized and other non-ASCII hostnames (#674).
• Domain-form SOCKS5 replies now decode the hostname after its length octet and read the port after the complete hostname, restoring accurate host and port diagnostics (#675).

Compatibility: this release has no public API changes and retains Java 8 compatibility.

Simple Java Mail 9.1.4 fixes file-stream ownership in EML conversion and includes Java 8-compatible dependency and release-tool updates.

Fixes

• EmailConverter.emlToEmailBuilder(File, ...) and EmailConverter.emlToMimeMessage(File, ...) now deterministically close the FileInputStreams they create after synchronous conversion.
• The caller-ownership contract is unchanged: overloads that accept an InputStream continue to leave caller-provided streams open.

Maintenance

• Updated SpotBugs annotations to 4.10.3.
• Updated the Central Publishing Maven Plugin to 0.11.0.
• Updated Objenesis to 3.6.

There are no public API changes. Java 8 remains the minimum supported runtime.
