Description

An array value passed as:

this_is_my_first_value,this_is_my_second_value

causes an NPE after the first token is returned:

java.lang.NullPointerException

The parse list being built contains "this". The sval field of the StreamTokenizer is indeed null - presumably because it has found the the underscore.

Workaround is to quote the string. See BEANUTILS-301 for an improvement request to allow _ as part of the default word character set.
