Please review a simple change to fix the use of non-ASCII characters in @param names.
The underlying problem was accidentally relying on `DocTree.toString()` for an `IdentifierTree` in `CommentHelper`. The fix is simply to get the underlying `Name` and call `toString` on that. There is some loosely related cleanup in `ParamTaglet`. I did see if it was possible to avoid excessive use of `String` in this part of the code, but that quickly became a rat-hole. The existing related test is updated to include this new case, of a Chinese identifier occurring in various places, similar to the test case in the original bug. ------------- Commit messages: - JDK-8271258: @param with non-ascii variable names produces incorrect results Changes: https://git.openjdk.java.net/jdk/pull/5168/files Webrev: https://webrevs.openjdk.java.net/?repo=jdk&pr=5168&range=00 Issue: https://bugs.openjdk.java.net/browse/JDK-8271258 Stats: 94 lines in 3 files changed: 63 ins; 6 del; 25 mod Patch: https://git.openjdk.java.net/jdk/pull/5168.diff Fetch: git fetch https://git.openjdk.java.net/jdk pull/5168/head:pull/5168 PR: https://git.openjdk.java.net/jdk/pull/5168
