the class ReportConverter method legacyLoad.

/**
     * Loads properties from the specified InputStream. The properties are of
     * the form <code>key=value</code>, one property per line. It may be not
     * encode as 'ISO-8859-1'.The {@code Properties} file is interpreted
     * according to the following rules:
     * <ul>
     * <li>Empty lines are ignored.</li>
     * <li>Lines starting with either a "#" or a "!" are comment lines and are
     * ignored.</li>
     * <li>A backslash at the end of the line escapes the following newline
     * character ("\r", "\n", "\r\n"). If there's a whitespace after the
     * backslash it will just escape that whitespace instead of concatenating
     * the lines. This does not apply to comment lines.</li>
     * <li>A property line consists of the key, the space between the key and
     * the value, and the value. The key goes up to the first whitespace, "=" or
     * ":" that is not escaped. The space between the key and the value contains
     * either one whitespace, one "=" or one ":" and any number of additional
     * whitespaces before and after that character. The value starts with the
     * first character after the space between the key and the value.</li>
     * <li>Following escape sequences are recognized: "\ ", "\\", "\r", "\n",
     * "\!", "\#", "\t", "\b", "\f", and "&#92;uXXXX" (unicode character).</li>
     * </ul>
     *
     * @param reader Reader from which to read the properties of this CrashReportData.
     * @return CrashReportData read from the supplied Reader.
     * @throws java.io.IOException if the properties could not be read.
