JPA delete query with multiple subqueries fails due to incorrect alias being generated

Issue

In a query like:

DELETE FROM Panel panelEntity WHERE
    panelEntity.posterCampaignId = osterCampaignId
    AND panelEntity.framePackagePrintId IS NULL
    AND panelEntity.clientId IN ( SELECT trtPanel.clientId FROM TrtPanel trtPanel )
    AND panelEntity.deltaStamp NOT IN SELECT trtPanel.deltaStamp FROM TrtPanel trtPanel )

The generated SQL looks like:

delete from PRD_PANEL where
    PPA_POSTER_CAMPAIGN_ID=?
    and (PPA_FRAME_PACKAGE_ID_PRINT is null)
    and (PPA_CLIENT_ID in (select trtpanel1_.TTP_CLIENT_ID from TEMP_TRT_PANEL trtpanel1_))
    and (panel0_.PPA_DELTA_STAMP not in  (select trtpanel2_.TTP_DELTA_STAMP from TEMP_TRT_PANEL trtpanel2_))

The panel0_ alias is stripped from the from element (as it should be), but is remaining on the 2nd where clause.
