I haven't encoutered this particular problem myself, though I remember
reading 
a post on this or the -java mailinglist not long ago where someone had
the 
same problem.

I did some google and didn't find anything conclusive, though I did find

someone having the same problem on Linux when running in a chrooted 
environment.

A suggestion which may or may not be correct is that it may be caused by
the 
linprocfs filesystem not being mounted (because it broke in chroot). Try

doing, as root:

   kldload linprocfs
   mount linprocfs /compat/linux/proc

But again I have personally not seen this problem. When I failed to have
a 
proper /proc filesystem for the Linux compatibility the result was the
JVM 
busy-waiting indefinitely rather than getting instability/errors. But
try 
that and see. If it doesn't fix it, write back.

(I am assuming it is the Linux JVM, running under emulation, which is
failing, 
given that it is compiling the standard library for the native JVM.)

So I did that....after SU'ing to root, the first command line worked
fine.  The second, however, produced an error as such:

	mount: linprocfs: No such file or directory


Someone else HAS to have had this problem?  Anyone?  What does everyone
else here do for JAVA support???

...OK so something new now.  I tried to "make install" again, and got this:

--------------------------------------------
frog# make install
===>  Building for jdk-1.4.2p6_4
ERROR: You have to have LINPROCFS mounted before
starting to build of native JDK 1.4.2.
 
You may do it by following set of commands:
 
# kldload linprocfs
 
and
 
# mount -t linprocfs linprocfs /compat/linux/proc
 
*** Error code 1
 
Stop in /usr/ports/java/jdk14.
frog# mount -t linprocfs linprocfs /compat/linux/proc
frog# make install
--------------------------------------------/

so I did as above (system suggested) and I'm seeing it building OK now.  I'll let the list know if I'm successful.

Can someone explain what it is that I had to do (above commands)??  Thanks!
