----------------------------------

             Summary: Non-breaking space causes alignment problems with text-align-last="justify"
                 Key: FOP-2438
                 URL: https://issues.apache.org/jira/browse/FOP-2438
             Project: Fop
          Issue Type: Bug
    Affects Versions: 1.1, trunk
            Reporter: Martin Doucha


Non-breaking spaces are not included in stretch factor calculation under special circumstances
but they are stretched by the resulting (oversized) stretch factor, leading to text overflowing
out of block. Those special circumstances are:
- text-align-last="justify"
- text-align="start" (or anything else other than justify)
- the non-breaking space has to get positioned on the last line of the block

Here's Knuth sequence for block "Test Test&nbsp;Test" with the above alignment settings:
<KnuthSequence [box w=17220, glue w=2500 stretch=1250 shrink=0, box w=17220, aux. box w=2500,
box w=17220, penalty p=-INFINITE w=0 (forced break, ??? (-1))]>
Notice that the second space is represented as box instead of glue with penalty.

Here's Knuth sequence for the same block but this time with alignment justify/justify:
<KnuthSequence [box w=17220, glue w=2500 stretch=1250 shrink=833, box w=17220, aux. box
w=0, aux. penalty p=INFINITE w=0, glue w=2500 stretch=1250 shrink=833, box w=17220, penalty
p=-INFINITE w=0 (forced break, ??? (-1))]>
This gets rendered correctly.
