AspectJ 1.7.1, LTW.
We use custom classloader that loads classes from byte[] array.
Class loading looks like this:
Class clazz = new MyClassLoader().defineClass(classPackage + className,
bytecode, 0, bytecode.length);
This code executes concurrently.
Classes from classPackage are not included for weaving in aop.xml.
Moreover, AspectJ reports that it can't find configuration for
MyClassLoader.
>From time to time we are getting the following exceptions:
SEVERE: my.package.MyClass
java.lang.NullPointerException
at org.aspectj.weaver.Dump.dumpOnExit(Dump.java:163)

Why AspectJ tries to weave this classes?
Why it fails with NullPointerException?
