Hi, I was able to narrow down further. Due to some reason in below case, I need object of RefNPtg class instead of currently being used RefPtg class.
But it looks like RefNPtg class is being used only while parsing a worksheet created by Excel. We do not use it while writing a formula created using POI. Any idea what is the difference between both classes?

In HSSF, "INDIRECT(UPPER($A7))" is encoded into [68, 6, 0, 0, -128, 65, 113, 0, 34, 1, -108, 0] whereas it should have been encoded into [76, 0, 0, 0, -128, 65, 113, 0, 34, 1, -108, 0]. This certainly points to issue in formula parsing. The above hack fixes the issue for this formula. I will try to dig deeper into above to understand the fix. Can some of POI developers also please respond whether such issue was seen before?

For this I have to use reference to another cell in same row inside the formula. I am using apache POI 3.7. I am using formula as such: "=INDIRECT(UPPER($A7))" for list for 7th row onwards in 3rd column. I am facing weird problem. For HSSF implementation, in Office 2003 and office 2007, for every row, formula refers $A$7. In Office 2010 I have not tested as of now. I want A8 to be referred for 8th row and A9 to be referred for 9th row and so on. In XSSF implementation, this works quite well. The same problem I am facing for conditional formatting too. Can someone please help? I have provided my implementation below. Thanks in advance!
