how to allow shorter lines in camel univocity fixed parser?

i have file like this

12345678
12345678
123

i have set two headers on UniVocityFixedWidthDataFormat with names num1 and num2 with length 5 and 3. the parser is able to read first two lines with ease, but it throws null pointer exception at third line. how can i tell my parser to read the shorter lines as well.

here is the stacktrace

java.lang.NullPointerException: null
