This would register the JNI methods every time this object is created, no? That
seems wrong. I think we need to export this as a static method and then call it
from ComponentsTestSuite::Initialize
(https://code.google.com/p/chromium/codesearch#chromium/src/components/test/ru...).

Done.

It's bad form to hold on to a JNIEnv object. Just call AttachCurrentThread() in
the destructor.

Done.
