James Dyer updated SOLR-4051:
-----------------------------
Description:
DIH Writes the last modified date to a Properties file using the default
locale. This gets sent in plaintext to the database at the next delta update.
DIH does not use prepared statements but just puts the date in an SQL Statement
in yyyy-mm-dd hh:mm:ss format. It would probably be best to always format this
date in JDBC escape syntax
(http://docs.oracle.com/javase/1.4.2/docs/guide/jdbc/getstart/statement.html#999472)
and java.sql.Timestamp#toString(). To do this, we'd need to parse the user's
query and remove the single quotes likely there (and now the quotes would be
optional and undesired).
It might just be simpler to change the SimpleDateFormat to use the root locale
as this appears to be the original intent here anyhow. Affected locales
include ja_JP_JP , hi_IN , th_TH
> DIH Delta updates do not work for all locales
