ZipExceptions on startup

[zapbot]

What steps will reproduce the problem?
1.Download, Unzip and start ZAP via zap.sh on Ubuntu 14.04 LTS
2.
3.

What is the expected output? What do you see instead?
ZAP appears to start but the console is full of stack traces.

Multiple stack traces in console that all resemble the following:

Strange.
No other info in the stack traces?
What version of Java are you using?

Not really.  There is one earlier stack trace that's similar but starts on org.zaproxy.zap.control.AddOn
instead of AddOnLoader.  This one also failed on the same place with ZipFile.open.

Also, I just tried running with sudo and I don't get the stack traces so I strongly
suspect a file permission issue.  Is this stack trace probably coming from reading
zip files in the "plugin" folder or could it be somewhere else?  


java -version
java version "1.7.0_65"
OpenJDK Runtime Environment (IcedTea 2.5.2) (7u65-2.5.2-3~14.04)
OpenJDK Client VM (build 24.65-b04, mixed mode, sharing)

I tried giving the entire ZAP folder all permissions and the problem still occurred,
so it doesn't appear to be any file permission issue within the distribution structure
itself.  

So a little more research on the stack trace (specifically I was looking for "at java.util.zip.ZipFile.<init>(ZipFile.java:215)"
to see what might cause this)....  plus looking into the source a bit.  It seems like
the issue is coming from the native code for opening and handling ZipFile and is likely
related to the handling of the temp space used by the implementation.

So it appears this is a platform specific bug.

The only cross-platform fix I saw described anywhere was to use a ZipInputStream directly
instead of a ZipFile.

ZAP will try to load add-ons (which are zip files) from 2 locations:
* <ZAP install>/plugin
* <user home>/.ZAP/plugin

Does the ZAP process have read access to both of those?

Are any of the files in those directories with .zap extensions zero length?

Hi,

I'm running into the same issue and unsure how to solve it except for running zap.sh
as root, any solutions?


Regards.
