Hi Chihiro,
- My proposal is not enough, so you should refine as below.
- Exception types in saveConvert() should be limited. Please do not use
`throws Exception`.
- I guess you use try-catch statement in serializePropertiesToByteArray
due to above checked exception.
It should be throw runtime exception when an exception occurs.
- Capacity of byteBuf (charBuf.length() * 5) should be (charBuf.length()
* 6)
because non 8859-1 chars would be "\uxxxx" (6 chars).
Also please leave comment for it because a maintainer might not
understand the meaning of multiplying 6 in future.
- `output.shouldNotContain("C:\\:\\\\");` in testcase is correct?
I guess you want to check "C\\:\\\\" is not contained.
- To check '\n', you can use Platform::isWindows as below:
output.shouldContain(Platform.isWindows() ? "line.separator=\\r\\n" :
"lineseparator=\\n");

Hi Yasumasa,
The line separator is not modified because it depends on the environment, but
the others have been modified.
Could you review this again?

Hi Chihiro,
Thank you for updating the webrev.
- You use BufferedWriter to create the output, however I think it would
be more simply if you use PrintWriter.
- Your change would work incorrectly when system property contains
mixture of ascii and non-ascii.
You can see it with "-Dmixture=aあi". It would be converted to "a\u0061\u3042",
it should be "a\u3042i".
- Currently key value which contains space char, it would be escaped,
but your change does not do so.
You can see it with "-D"space space=blank blank"".
- You should not use String::trim to create String from ByteBuffer
because property value might be contain blank in its tail.
You might use ByteBuffer::slice or part of ByteBuffer::array for it.
- Did you try to use escaped chars in jtreg testcase? I guess you can set
multibytes chars (e.g. CJK chars) with "\u".
In case of mixture of Japanese (Hiragana) and ASCII chars, you can embed
"-Dmixture=a\u3042i" to testcase. (I'm not sure that...)
- In test case, I recommend you to evaluate entire of line.
For example, if you want to check line.separator, you should evaluate
as below:
output.shouldContain("line.separator=\\n");
Thanks,
Yasumasa
