Suppose having an Entity class with fields like these (with secod letter in UpperCase): tStart, tEnd, tModify, etc...
If you have accessType PROPERTY the Metamodel generated is missing these attribute
The error is in method
org.hibernate.jpamodelgen.util.StringUtil#checkPropertyName
the method "gettStart" is the correct getter method for property tStart (see javabeans spec) but the check fail to recognize it
The metamodel is generated correctly if the accessType is FIELD
