Ryan Wisnesky commented on LANG-1368:
-------------------------------------
I’m sorry, but this has been lost to time. I can add that it was using the
eclipse compiler for java 8 on a Mac.
> HashCodeBuilder.append incorrect behavior with chains of nulls
> --------------------------------------------------------------
>
> Key: LANG-1368
> URL: https://issues.apache.org/jira/browse/LANG-1368
> Project: Commons Lang
> Issue Type: Bug
> Reporter: Ryan Wisnesky
> Priority: Minor
>
> I have a 7-way choice/sum/variant class, so that 6 of its 7 fields are null
> in each object of that class. When using HashCodeBuilder's reflective
> hashCode, a 10k line java project works correctly. When using
> HashCodeBuilder.append instead, sequential calls to append with a null
> argument cause the returned hashCode to be inconsistent with EqualsBuilder.
> Correct behavior can be restored by appending a dummy non-null field
> initially:
> new HashCodeBuilder()
> .append(true) //bad return value
> without this dummy call
> .append(chc1)
> ...
> .append(chc7)
> .toHashCode();
>
