The process I am running using JRE is an RMI server. When
attempting to access a path that is a removable drive (disk
drive A:, or local JAZ drive) jre displays a modal dialog
box saying "there is no disk in the drive, please insert
a disk into drive DRIVE".   This happens on any type of
file IO (File.isDirectory(), new FileInputStream(), etc.) so
I have not included specific code.  If you click abort, you
get the IOException.

Maybe this is not a bug, but my RMI server blocks... what I
need is for the exception to be thrown without displaying the
modal dialog box, but I can't figure out how to eliminate this
behavior.

Thanks

REVIEW NOTE 3/10/99 - User responded with more information

Below is a sample that easily re-creates it, and below that is my actual
code.   But after further searching, I found this bug was already
reported:

	> bug id: 4089199
	> location: http://developer.java.sun.com/developer/bugParade/bugs/4089199.html

This really, really needs to be fixed or we need a workaround!!! It would be
OK if
it just stopped the executing thread, but I am seeing that it blocks my RMI
server,
rendering it useless (this happens if an automatic backup gets kicked off
and the
admin forgets to put in a jaz drive, for example).   
 
Help!!!
