Null Boolean Values in Hibernate Search

I ran across this problem when using Hibernate Search to build an index for pre-existing data. Our data contains a Boolean field recommended that, in our database, can contain null values. When Search attempted to index documents with null Boolean values, it crashed, showing a NullPointerException at BooleanBridge.java@20. When I looked through the source, it appears that the code reads:

Code:

Boolean b = (Boolean) object;
return b.toString();

As such, a null Boolean value was crashing on the toString() method. The fix that I implemented was changing

Code:

return b.toString();

to

Code:

return (b == null) ? null : b.toString();

This issue does not appear to happen in any of the other Bridges, they already seem to handle null values. I wanted to verify that this is indeed a bug before submitting the issue to JIRA.

Thank you.

You are correct

I fixed in in SVN
You can use a @FieldBridge in the meanwhile if you don't want to use the SVN HEAD version
