[3.1 TCK Challange] entity classes used by testcase does not conform to java bean standard

in files [jpa/core/entityManager/Order.java](https://github.com/jakartaee/platform-tck/blob/10.0.x/src/com/sun/ts/tests/jpa/core/entityManager/Order.java) and [jpa/core/entityManager2/Order.java](src/com/sun/ts/tests/jpa/core/entityManager2/Order.java) have methods getdescription and setdescription which doesn't conform to java been specification.

Start with src/com/sun/ts/tests/jpa/core/entityManager/Order.java and src/com/sun/ts/tests/jpa/core/entityManager2/Order.java. Inspect the getdescription and setdescription methods against the JavaBeans naming convention, then run the relevant JPA TCK tests to confirm the entity classes conform.
