Problem with JodaTime

Hi,

I noticed the following Problem with a POJO I use to encapsulate Values.

java.lang.NullPointerException
	at org.joda.time.tz.CachedDateTimeZone.getInfo(CachedDateTimeZone.java:143)
	at org.joda.time.tz.CachedDateTimeZone.getOffset(CachedDateTimeZone.java:103)
	at org.joda.time.format.DateTimeFormatter.printTo(DateTimeFormatter.java:722)
	at org.joda.time.format.DateTimeFormatter.printTo(DateTimeFormatter.java:535)
	at org.joda.time.format.DateTimeFormatter.print(DateTimeFormatter.java:671)
	at org.joda.time.base.AbstractInstant.toString(AbstractInstant.java:424)
	at org.joda.time.base.AbstractDateTime.toString(AbstractDateTime.java:314)
	at java.lang.String.valueOf(String.java:2994)
	at java.lang.StringBuilder.append(StringBuilder.java:131)

and found this 

https://github.com/JodaOrg/joda-time/issues/307 <https://github.com/JodaOrg/joda-time/issues/307>

Help is really appreciated.

best,
Stephan

Hi Robert,

thanks for the fast response. The following line fixed the problem (maybe a good topic for the docs), because I thought JodaTime is supported out of the box.
Buts I think thats only the case with the JacksonParser.

this.env.addDefaultKryoSerializer(DateTime.class, JodaDateTimeSerializer.class);
best,
Stephan

Hi Stephan,

Can you post the list of fields in the POJO and the full exception (so that
I can see which serializer is being used).

In general, to fix such an issue, you have to implement a custom serializer
for the field that is causing the issues.
