Class file import should be resilient against broken class files

[codecholeric]

Currently one broken file evil.class breaks the whole import causing an exception. It would be more convenient, to just log a warning and move on.
How to reproduce:

echo "broken" > /some/test/folder/Evil.class
cp some.GoodClass.class /some/test/folder

then

JavaClasses classes = new ClassFileImporter().importPath(Paths.get("/some/test/folder"));

Expected: some.GoodClass to be imported
Actual: Import dies with an exception
