What is your runtime environment?
I also think I may have seen this when there are duplicate libraries on
the classpath, just not sure where :-\
Switch to debug logging and see if there is anything else in the logs
that may throw some more light on this.

Hi
I'll try to have a quick look to check few thing but a sample showing it
would be great. A if (!= null) would surely work for you but is not really
compatible with this logic (well not alone ;))

Hi,
I think we use it quite "normally". The problem arised when we upgraded
a library (vaadin from 7.1.10 to 7.2). However the vaadin jar does not
contain any beans.xml file.
How can I investigate more?
As Class#getClassLoader() can be null, I think it would be a good idea
to check for this, e.g. in the comparator. Should I submit a patch?
Cheers.
Stan.

Hi
how do you use it? Charset can't be in this class list normally

Hello everyone,
We are using Tomee (and OpenEJB) 1.6.0.2 and we have a problem with the
startup of OpenEBJ:
a NPE occurs in the CdiScanner: on line 260 of the CdiScanner.java,
there
is a comparison between 2 ClassLoaders. (see below).
257 final ClassLoader cl = clazz.getClassLoader();
...
260 if (!filterByClassLoader
261 || comparator.isSame(cl) || (cl.equals(scl) &&
startupObject.getWebContext() == null)) {
I have debugged step by step and found that the NPE occurs when the
variable clazz is
the class java.nio.charset.Charset. In this case, the classloader is
null
and the test
on lines 260/261 fails.
I have patched the line 261 to check whether cl is null (according to
the
Class API, wenn a class
is loaded with the Bootloader, it is allowed to return null to the
method
Class#getClassLoader);
and it works perfectly. (It would be probably a better idea to check for
null in the comparator).
Have other Tomee/OpenEJB users encountered the same problem? It seems to
me strange that the
class java.nio.charset.Charset is being scanned.
Thanks for your help!
Cheers,
Stan.
