Buby

Buby no longer works with 1.6.20 (results in error: no implicit conversion of nil into String); 1.6.19 and below works fine.

We're not seeing any problems running the Buby extension in the 1.6.20 release. If you're still seeing problems, please can you provide exact repro steps? Please also note that to use Buby when launching Burp from the command line, you must ensure that your working directory is the directory containing the Burp executable. Buby performs some manipulation of the Java classpath based on the working directory, and this doesn't work properly if you invoke Burp from a working directory other than the location where Burp resides.

This seems to only happen in OSX w/ 1.6.20 and higher. Java = 1.8.0.45 w/ any Jruby (9.0,1.7.x). Windows works fine; have not tried OSX.

Tried on 4 different Macs with no luck.

Found the problem... Partially a user fault I suppose for not being tidy enough, but when one does not clean out all the old burp*.jarS, bad things will happen...with buby now. (Re)Solution: start BSP 1.6.20+ inside a CLEAN directory. (or just delete all the hold burp*.jar files in your $BURP_HOME.

I'm seeing this problem on 1.7.17 on OS X. How exactly did you solve this? Where are the old burp*.jar files?
