Why do I receive Java error messages when using the SYSTEM command?

When I use the command:

str1 = 'C:\Progra~1\WinZip\Wzzip "C:\Documents and Settings\mchechelnitsky.000\Desktop\BRIEFCASES\AccessDatabases"  "g:\avm\Input_Database\Operational_Database_Input.mdb"';

system (str1);

I receive the following error:

The above Java error is probably because of a message that should be printed to the screen but fails.

This bug has been fixed in Release 14 Service Pack 3 (R14SP3). For previous product releases, read below for any possible workarounds:

We have verified that there is a bug in MATLAB 7.0 (R14) when using the SYSTEM command to execute a command that would update the system command window dynamically.

To work around this issue, use the SYSTEM command with output variables. For example:

str1 = 'C:\Progra~1\WinZip\Wzzip "C:\Documents and Settings\mchechelnitsky.000\Desktop\BRIEFCASES\AccessDatabases"  "g:\avm\Input_Database\Operational_Database_Input.mdb"';

[s,r] = system(str1);

This will supress printing a message to the screen.
