I've found a bug in AdaptiveClassLoader.loadResourceFromZipfile. This
method returns an InputStream with zipfile.getInputStream from within the
main block of a try/catch/finally statement and then calls zipfile.close
from within the finally block of the same. When I commented out the
finally block of the try/catch/finally, it works fine. (This is how it
was up through 1.1b3.)
Grossly paraphrased it's doing this:
try {
...
return zipfile.getInputStream(entry);
...
} catch (IOException ex) {
return null;
} finally {
...
zipfile.close();
...
}
