keytool -certreq output contains inconsistent line separators

Certificate signing requests generated with keytool on Linux generate CRLF at the end. This is a regression to JDK 7, which used plain '\n' to separate lines. This is an interoperability issue with non-Java tools.

Steps to Reproduce:
$ keytool -genkeypair -alias dummy -keyalg RSA -keysize 2048 \
    -sigalg SHA256withRSA \
    -dname "CN=dummy.example.com, OU=Dummy, O=Dummy, L=Cupertino, ST=CA, C=US" \
    -validity 3652 -keypass passphrase -keystore keystore \
    -storepass passphrase
$ keytool -keypass passphrase -storepass passphrase -certreq -v -alias dummy -keystore keystore -file csr.txt
$ file csr.txt
csr.txt: RFC1421 Security Certificate Signing Request, ASCII text, with CRLF, LF line terminators

Note the "CRLF, LF line terminators" output of file.

Expected:
$ file csr.txt
csr.txt: RFC1421 Security Certificate Signing Request, ASCII text

A plain "jtreg"-like Java test showing the issue is attached.

Expected output:
DEBUG: Verifying whether cert request is consistent with platform CRLF...
