问题
Can Thread.getContextClassLoader() be null ? The javadoc is not really clear.
Should a library take this case into account ?
Update: the reason I asked is that beansbinding.dev.java.net does not work in this case (and my code does setContextClassLoader(null)
回答1:
Java threads created from JNI code in a non-java thread have null ContextClassloader unless the creator explicitly sets it.
Also in such context Thread.currentThread() returns null.
回答2:
Yes you should, someone could have called Thread.setContextClassLoader(null) and your library IMO should be able to deal with that.
