source and excel to re-produce the bug

If I apply style with large font to cell, i.e. "insert large text", the resulting excel does have row tall enough to contain the text (font) but row.getHeight() still returns original height value.

This happens even after reading the excel back (so it's consistent, nothing magic there either :=)

But, after saving the resulted excel with Excel (2003) and reading THAT back to POI, the height-attributes are set to match the font, as expected.

Tested with latest r729456. Source and excels to reproduce attached.

Another case related to here; if I have cell having "wrap text" option set, and row was therefore stretched, the getHeight() returns that stretched size, even after replacing the row contents with something that fits in "single height".

I.e. the height value is not (re-)set here either.

As far as I see you are not adjusting the height of the row anywhere and Apache POI does not try to auto-size row-height based on fonts used in any cell. 

So by specifying the row-height via

row.setHeightInPoints((short)30);

before writing the file you should be able to get the expected behavior.
