Subject: modified multipartinputstream so that it is not that much dependent on the one and... 
X-Git-Tag: 6.7.0.beta1~451^2~33
X-Git-Url: https://source.dussan.org/?a=commitdiff_plain;h=b5d7536b473abf61ade51193ebf3f6e53258da8a;p=vaadin-framework.git

modified multipartinputstream so that it is not that much dependent on the one and only function where it is used. Also modified tests to work somewhat sane and removed some invalid tests.
