Searching the Web using this message reveals that the 1008813135
corresponds to the sequence of characters "<!DO" and indicates that
the server is trying to load the JAR file as the beginning of an
HTML / XML page, presumably with test beginning with "<!DOCTYPE".
Various people suggested clearing the Java cache, but that doesn't fix
the problem.

If you could, it would be very helpful to see what the "class file"
really contains.

One suggestion of doing this:

java.lang.ClassFormatError: Incompatible magic value 1008813135 in
class file mypackage/m
  at java.lang.ClassLoader.defineClass1(Native Method)
  at java.lang.ClassLoader.defineClassCond(Unknown Source)
  at java.lang.ClassLoader.defineClass(Unknown Source)

Grab the source code to java.lang.ClassLoader, rewrite the
java.lang.ClassLoader class to have defineClass catch said error and
dump the "class" to some file, and hook this modified classloader into
the bootstrap class path.
