New issue 5439 by neskazu: Exception in thread "stp-thread"
java.nio.BufferUnderflowException when page loads on remote Opera browser
http://code.google.com/p/selenium/issues/detail?id=5439

What steps will reproduce the problem?
1. On the local PC create WebDriver with "new OperaDriver(capabilities)"
and single capability opera.autostart set to false
2. On the remote device (set-top box in our case) load opera:debug connect
to PC
3. Connection is established. It is possible to get page source, etc...
4. On the remote device load another page: in our case widget representing
SVG application. It takes several minutes for application to load and the
DOM tree changes several time during it.

Exception is thrown in stp-thread of local WebDriver

Exception is thrown when DOM tree changes at different phases of
application loading and quite rarely not thrown at all.
Stack Trace is just printed to the std.err, no WebDriver methods are called
at that time by the client app.

After such exception any WebDriver methods invocation finish with timeout.

In case BufferUnderflowException does not appear during page loading, it is
possible to access the page source and web elements on it.
The page size is ~1.5 MB.

Tried to reproduce with Opera Dragonfly on the same environment and same
application:
Dragonfly obtains the page in most of the cases (sometimes it shows
Out-of-Memory error). So, seems that Dragonfly receives the DOM tree
correctly and since the remote device and application are the same, the
issue should be on the WebDriver side.

Selenium version: 2.31.0 or latest opera web driver code from master branch
on GitHub (3 Apr 13)

OS: Remote: Linux, Local: Windows 7
Browser: Opera
Browser version: Opera/9.80 (Linux mips; U; en) Presto/2.10.250
Version/11.60

Unfortunately it's not possible to share any part of the application.
