Description Richard W.M. Jones 2014-03-07 13:33:07 UTC

+++ This bug was initially created as a clone of Bug #1073906 +++

Description of problem:

Using the inspect_list_applications2 function causes java.lang.ArrayIndexOutOfBoundsException to be thrown.

Version-Release number of selected component (if applicable):

libguestfs-java-1.25.42-1.fc21.x86_64

How reproducible:

100%

Steps to Reproduce:

Download InspectVM.java file attached.

Compile it like this:

javac -classpath /usr/share/java/libguestfs.jar InspectVM.java 

To test this you will need any Linux disk image.  eg. Build one using
virt-builder:

virt-builder fedora-20

Run the program on this disk image:

$ java -classpath /usr/share/java/libguestfs.jar:. InspectVM fedora-20.img 
Root device: /dev/sda3
  Product name: Fedora release 20 (Heisenbug)
  Version:      20.0
  Type:         linux
  Distro:       fedora
java.lang.ArrayIndexOutOfBoundsException: 231

It shouldn't print the ArrayIndexOutOfBoundsException error.
