This is great and will be very helpful while debugging! Only the output is
very hard to read. How about this? Just some new lines and indention:
```
Cannot load user class: com.foo.bar.SomeClass
ClassLoader info:
URL ClassLoader:
url: 'http://localhost:26712/some/file/path'
file: '/tmp/flink-url-test2825910185710886145.tmp' (valid JAR)
file: '/tmp/flink-url-test4914469684250387785.tmp' (invalid JAR:
error in opening zip file)
file: '/tmp/flink-url-test5462325335282720117.tmp' (missing)
```
I think users are less prone to read Exception messages when they have to
scroll horizontally. We usually don't include newlines in our Exceptions.
