reveng *.java emitter does not escape java keyword 'return' as variable name

<table name="oc_return_history">
<foreign-key constraint-name="FK_oc_return_history__return_id" foreign-table="oc_return">
<column-ref local-column="return_id" foreign-column="return_id"/>
<!-- this breaks the generator trying to name local variable as a java keyword -->
<many-to-one property="return"/>
</foreign-key>
</table>

The expected output would be:

private Return _return;

but actual output is:

private Return return;
