Hi, Please review the following patch which will:
- Enhance the java.nio.file.spi.FileSystemProvider abstract class to include the methods - public boolean exists(Path path, LinkOption... options) - public <A extends BasicFileAttributes> A readAttributesIfExists(Path path, Class<A> type, LinkOption... options) This change allows for providers to provide optimizations when the file's attributes are not needed. Mach5 tiers 1 - 3 run clean with this change The CSR may be viewed at [JDK-8283336](https://bugs.openjdk.org/browse/JDK-8283336) Best, Lance ------------- Commit messages: - Add exists and readAttributesIfExists methods to FileSystemProvider Changes: https://git.openjdk.org/jdk/pull/9249/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=9249&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8283335 Stats: 342 lines in 10 files changed: 177 ins; 129 del; 36 mod Patch: https://git.openjdk.org/jdk/pull/9249.diff Fetch: git fetch https://git.openjdk.org/jdk pull/9249/head:pull/9249 PR: https://git.openjdk.org/jdk/pull/9249
