[jdk11u-dev] RFR: 8274893: Update java.desktop classes to use try-with-resources [v2]

[Timofei Pushkin]

> Backport of [JDK-8274893](https://bugs.openjdk.org/browse/JDK-8274893) from JDK 17, for parity with Oracle 11.0.27.
> 
> The only conflict was trivial: in imports of `JEditorPane` which uses * imports in this release, so no change was needed.
> 
> Testing: GitHub CI, `jdk_imageio` test group locally (mac/arm64)
