Hi all.

Just a heads-up for those using java8-bytecode with lambdas

I've compiled my project with:

<arg>-Ydelambdafy:method</arg>
<arg>-Ybackend:GenBCode</arg>
<arg>-target:jvm-1.8</arg>

And having scala-java8-compat_2.11 on the class-path, to achieve: https://github.com/scala/scala/pull/4463

Then I'm seeing this:

java.lang.ArrayIndexOutOfBoundsException: 22321
       at com.thoughtworks.paranamer.BytecodeReadingParanamer$ClassReader.<init>(BytecodeReadingParanamer.java:451)
       at com.thoughtworks.paranamer.BytecodeReadingParanamer$ClassReader.<init>(BytecodeReadingParanamer.java:431)

       at com.thoughtworks.paranamer.BytecodeReadingParanamer.lookupParameterNames(BytecodeReadingParanamer.java:100)
       at com.thoughtworks.paranamer.CachingParanamer.lookupParameterNames(CachingParanamer.java:75)
       at com.thoughtworks.paranamer.CachingParanamer.lookupParameterNames(CachingParanamer.java:68)
       at net.liftweb.json.Meta$ParanamerReader$.lookupParameterNames(Meta.scala:89)

The issue is solved: https://github.com/paul-hammant/paranamer/issues/17

But isn't in maven-central yet.

I've tested 2.7.1-SNAPSHOT and it works.
