Hi Andrea,

using ojdbc7 does not fix this issue.

I tried to set the schema explicitly with the hibernate property hibernate.default_schema. With this I got the schema validation to pass. But as we use synonyms from multiple tables I have to use wildcards (%) in the schema name. And this leads to errors such as
java.sql.SQLSyntaxErrorException: ORA-00911: invalid character
while accessing the data.

Then I tried to activate synonyms with the hibernate property hibernate.synonyms set to true. But with that the validation fails again.

Caused by: org.hibernate.tool.schema.spi.SchemaManagementException: Schema-validation: missing column [id] in table [TESTME]
