<p style="margin-top:0;margin-bottom:10px;; margin: 10px 0 0 0">In one specific situation the Hibernate fails to parse the JPQL query correctly. When there is "select" query with "left outer join" with "select size" on join part - the hiberante falls with "String index out of range: -5" exception. </p>
<p style="margin-top:0;margin-bottom:10px;; margin: 10px 0 0 0">I first encountered this with MSSQL database, and then succesfully reproduced the bug with HSQL database. I will attach to this issue a simple maven project that reproduces this bug. </p>
<p style="margin-top:0;margin-bottom:10px;; margin: 10px 0 0 0">The JPQL query, that makes hibernate fall looks like this: <br /> "Select a, b.size from EntityA a left outer join a.entityBList b";</p>
