There are few places in code where manual `for` loop is used with Iterator to iterate over Collection or Array. Instead of manual `for` cycles it's preferred to use enhanced-for cycle instead: it's less verbose, makes code easier to read and it's less error-prone. It doesn't have any performance impact: javac compiler generates similar code when compiling enhanced-for cycle.
One strange thing I also noticed is static field `sun.tools.jstat.Parser#reservedWords`, which filled in `Parser` constructor. Reworked to initialize it once. ------------- Commit messages: - [PATCH] Use enhanced-for instead of plain 'for' in jdk.jcmd Changes: https://git.openjdk.java.net/jdk/pull/5673/files Webrev: https://webrevs.openjdk.java.net/?repo=jdk&pr=5673&range=00 Issue: https://bugs.openjdk.java.net/browse/JDK-8274261 Stats: 44 lines in 6 files changed: 0 ins; 14 del; 30 mod Patch: https://git.openjdk.java.net/jdk/pull/5673.diff Fetch: git fetch https://git.openjdk.java.net/jdk pull/5673/head:pull/5673 PR: https://git.openjdk.java.net/jdk/pull/5673
