ImageIO objects, like ImageReader, ImageWrite, ImageInputStream and ImageOutputStream, should implement AutoClosable.
There is a risk of keeping resources opened longer than needed (or even run into a resource leak with long running processes) as the user cannot use try-with-resources currently. The fact that there is a `dispose()` method to be called is easily missed, as people tend to look for `close()`. This is not a big change, but it is useful for those working with ImageIO. ------------- Commit messages: - Implements AutoCloseable Changes: https://git.openjdk.org/jdk/pull/12098/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=12098&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8302281 Stats: 20 lines in 3 files changed: 14 ins; 0 del; 6 mod Patch: https://git.openjdk.org/jdk/pull/12098.diff Fetch: git fetch https://git.openjdk.org/jdk pull/12098/head:pull/12098 PR: https://git.openjdk.org/jdk/pull/12098
