This class Sample1 does NOT create a database table,
and no Exception is thrown

If you change the property name to "ychange" everything
works fine...

This class Sample2 creates a database table just fine...

---------------------------------------------------------------------------------

When the class below is executed, only one database table
gets created, not 2 tables as to be expected...

Only the table Sample2 table gets created,
because in Sample1 the property name is called "change"
no table gets created.

If you change the property name in Sample1 to "ychange",
two database tables get created as would be expected.

Its just when you call a property name "change" that
it seems like weird things happen.

Try putting backticks around it

<property name="`change`"/>
