[jira] Created: (BEANUTILS-302) NPE in ArrayConverter when converting a non-quoted string with underscores to a string array

NPE in ArrayConverter when converting a non-quoted string with underscores to a string array
--------------------------------------------------------------------------------------------

                 Key: BEANUTILS-302
                 URL: https://issues.apache.org/jira/browse/BEANUTILS-302
             Project: Commons BeanUtils
          Issue Type: Bug
          Components: ConvertUtils & Converters
    Affects Versions: 1.8.0-BETA
         Environment: All
            Reporter: Martin Bartlett
             Fix For: 1.8.0-BETA


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
	at org.apache.commons.beanutils.converters.ArrayConverter.parseElements(ArrayConverter.java:440)
	at org.apache.commons.beanutils.converters.ArrayConverter.convertToCollection(ArrayConverter.java:343)
	at org.apache.commons.beanutils.converters.ArrayConverter.convertToType(ArrayConverter.java:279)
	at org.apache.commons.beanutils.converters.AbstractConverter.convert(AbstractConverter.java:171)
	at org.apache.commons.beanutils.converters.ConverterFacade.convert(ConverterFacade.java:60)
	at org.apache.commons.beanutils.BeanUtilsBean.convert(BeanUtilsBean.java:1079)
	at org.apache.commons.beanutils.BeanUtilsBean.copyProperty(BeanUtilsBean.java:437)
	at org.apache.commons.beanutils.BeanUtilsBean.copyProperties(BeanUtilsBean.java:270)
	at org.apache.commons.beanutils.BeanUtils.copyProperties(BeanUtils.java:137)

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.
