It was called 9 times during bootstrap because of:

1. SimpleValue#isValid
2. Property#getType
3. SimpleValue#getType
4. Property#getCascadeStyle
5. AttributeFactory#determineAttributeMetadata
6. Column#getSqlTypeCode

Some of the above like Property#getType are called multiple times.

I considered the Type and the Properties parameters and made a copy of the Properties to make sure we capture the Type building context.

If you want to take a look on my fix, check out this Pull Request. It's not a big change and all tests run successfully too.
