Hello there,
NB6 (tested on RC1) has some problem with formatter.
Look on this example:

Number transAfterCnt = (Number) em.createQuery(
        "SELECT COUNT(t) " +
        " ...many lines here..." +
        " ...final Sttring "
        )
        .setParameter(1, loan)
        .setParameter(2, txDate)
        .setParameter(2, txId)
        .getSingleResult();


And this is what NB6 formatter does:

Number transAfterCnt = (Number) em.createQuery(
        "SELECT COUNT(t) " +
        " ...many lines here..." +
        " ...final Sttring ").setParameter(1, loan).setParameter(2, txDate).setParameter(2, txId).getSingleResult();

It is happening with everything which looks like the above, every time you have something like

SomeClass s =  something()
 .someMethod1()
 .someMethod2() 
 .someMethod3()
 .someMethod4()
 .someMethod5();

[alt+shift+f]

SomeClass s =  something().someMethod1().someMethod2().someMethod3().someMethod4().someMethod5();

It is formatting everything to be in one line, very problematic issue :(
