        MySQL is funny when it comes to timestamps and dates. More specifically, for a DDL statement like 'MYCOLUMN timestamp(3)': - MySQL 5.6.4+ has support for timestamps/dates with millisecond (or smaller) precision. The DDL above works and the data in the table will have millisecond precision - MySQL before 5.5.3 allows the DDL statement, but ignores it. The DDL above works but the data won't have millisecond precision - MySQL 5.5.3 before [version] after 5.6.4 gives and exception when using the DDL above. Also, the 5.5 and 5.6 branches of MySQL are both actively developed and patched. Hence, when doing auto-upgrade/creation of the Flowable tables, the default MySQL DDL file is used and all timestamps/datetimes are converted to not use the millisecond precision by string replacement done in the method below. If using the DDL files directly (which is a sane choice in production env.), there is a distinction between MySQL version before 5.6.
