Here's some of the changes in 3.3.0 that I tracked down when I was working soot processing with lambdas recently:</div>

<div class="gmail-m_1162042272601806350PlainText">Hi all,<br>
<br>
I’m running soot on a jar and it’s barfing with an error saying “Failed to convert” on a method that returns a java.util.function.Function from a lambda expression. The bytecode involves invokedynamic and I’m wondering if soot has trouble on that sort of code,
and if so, what a good approach to dealing with it is.<br>
<br>
Unfortunately I can’t share the code in question but might be able to reduce it later if it helps or if this behavior is unexpected.<br>
<br>
Thanks,<br>
Dan<br>
