Hibernate adds alias for PARTITION keyword

For example :

{{@Formula(" ROW_NUMBER() OVER( PARTITION BY VOUCHER_MASTER_ID ORDER BY SIGN(amount) DESC , ABS(amount) ASC)")
private Integer lineNumber;}}

Causes this sql:
{{ ROW_NUMBER() OVER( voucherlin21_.PARTITION BY voucherlin21_.VOUCHER_MASTER_ID ORDER BY SIGN(voucherlin21_.amount) DESC , ABS(voucherlin21_.amount) ASC) AS formula0_20_,}}

By removing alias from PARTITION generated SQL works properly
