NPE at com.google.inject.InjectorImpl$LateBoundConstructor.get() #222

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
This bug was reproduced against guice "snapshot20080713"

Repro steps:

Check out warp-servlet/tags/warp-servlet-0.9_1 and run "ant assemble.jar".
The build will fail because InjectorImpl.java:478 throws a
NullPointerException. The full stack-trace follows:

FAILED: continueConvAcrossRequests
com.google.inject.ProvisionException: Guice provision errors:

   1) Error at [unknown source]:

It's not clear to me what this test is doing wrong. Guice should throw a
cleaner error message.

I tried debugging this further but quickly got lost. It seems that somehow an
injector context with a null injectionPoint gets used. It's not clear whether 
we're
reusing a dead context or never initializing it properly in the first place.

This looks to me like the same problems as issue #136.

Is there a workaround for this issue?

Followed instructions but everything worked.  Also tried replacing the packaged 
guice jar with guice-3.0-rc2 but it still worked.
