Recompile jodatime?

Question

This is my first time using jodatime and i've got a stackoverflow error that i have no idea how to fix. I'm creating an android app that needs to be able to display the days between when a sqlite record was created and today. As far as i can tell everything is working correctly except jodatime. I got this error when building the project

[2010-08-10 02:08:50 - Grow Journal Beta] processing org/joda/time/DateTimeUtils.class...

[2010-08-10 02:08:50 - Grow Journal Beta] processing org/joda/time/DateTimeZone$Stub.class...

This is the logcat:

After looking around a bit i figure i just need to recompile the jodatime binary my self. I've been using eclipse, I created a new project, and imported the jodatime source. When I attempt to compile I get this in the console:

Usage: java org.joda.time.tz.ZoneInfoCompiler <options> <source files>

where possible options include: -src Specify where to read source files -dst Specify where to write generated files

Not really sure where to go from here. Any help would be greatly appreciated. Thanks for your time.

DateTimeZone.class source is Here

Answer 1

The problematic recursion is apparently between DateTimeZone.getDefault and DateTimeZone.forID. However, the stack line numbers don't seem to line up with the Joda source code I see here. And in that code, the DateTimeZone.getDefault() method doesn't look at the system properties ... that stuff happens in a static initializer.

It seems like the Android codebase uses a tweaked version of JodaTime.

Anyway, it looks like calling JodaTime.setDefault(...) might be a workaround. Also, check that the "user.timezone" system property has been set.

(I don't think recompiling / using the standard JodaTime is the right strategy. The Android tweaks ... whatever they are ... are probably there for a reason.)

EDIT

Revisiting this, it transpires that this was a bug in JodaTime 1.6.1 on some platforms (Android, Google-Apps). The issue tracker shows it as fixed in the JodaTime 1.6.2.

Answer 2

Why can't you use something like:

SELECT julianday('now') - julianday('1776-07-04');  

In your query ?

Answer 3

I just have the same problem, I think it is a bug in joda-time 1.6.1, because all runs well whis 1.6 version. I posted a bug report on the joda-time bug tracker and I use 1.6 version.
