How to adjust text field with stretch with overflow

[blessed_spot]

I use ireport 4.5.1 (I know it's so so old but it's at work and I don't have authority to upgrade it). 
Anyway, I have a text field with following value:

    $F{field1} + " — " + $F{field2}
Both field1 and field 2 are of java.lang.string type.
Since neither field1 nor field2 has consistent length, I have checked the stretch with the overflow property as TRUE. But the problem is that when I have a long text for field2 the rest of it comes below field1 while I need it begin right below field2.

Actually, it appears like: 

    something for field1 — something very long 
    for field2

While I need it like:

    something for field1 — something very long 
                           for field2
and if I put  $F{field1} in a separate text field, since it doesn't have a fixed length, sometimes an extra space appears after $F{field1} or if I set its stretch with overflow property as TRUE, $F{field1} appears in two lines, which I don't like it either.
Generally, I need $F{field1} appear in one line with only one space after that and $F{field2} to split in two lines, if its length is too long, and appear as I described above.
Is there any way to do that?

When you enter 45 as the parameter value, it displays it as 

    GD$ — java code to iReportGENERAL SAFETY
    TRAINING/INJURY & ILLNESS PREVENTION
    PROGRAM

while I need it as :

    GD$ — java code to iReportGENERAL SAFETY
          TRAINING/INJURY & ILLNESS PREVENTION
          PROGRAM
