roblem1: Unable to perform sort operation in java cache viewer's table.
Problem2: Unable to see scroll bar when UI is minimized.
Problem3: Unable to expand java cache viewer's table header beyond certain range.

STEPS TO REPRODUCE

1. Run the below command to invoke Java Cache Viewer.
     >>javaws -viewer

2. This will launch Java Cache Viewer.

Problem1:

- Make sure that you have some(atleast 2)jnlp application in java cache
  viewer.(Refer webstart test case in order to have it)
- Go to resources tab.
- Left click on table header to sort the table data.
- "Size" and "Modified" are sorted only in ascending order (they should
  be sorted in descending order also)
- "Name" and "URL" are sorted only in ascending order (they should be
  sorted in descending order also)

Problem2:
- Make sure that you have some (at least 2) jnlp application in java
  cache viewer
- Go to resources tab
- Horizontally minimize the java acche viewer UI until you see only
  "Name" header
- Expected result: We should see horizontal scroll bar in order to
  scroll and see the reamaining column headers such as
  URL,Modified,Size etc.

Problem3:
- Make sure that you have some(atleast 2)jnlp application in java cache
  viewer.(Refer webstart test case in order to have it)
- Go to resources tab.
- Expand "Name" column header as much as possible. We won't be able to
  expand beyond certain point.
- Expected result: We should be able to expand fully.
