Tim,

When I compare the versions of linux_base, both boxes have the same version.
On the first machine I don't see the warning:

bash-2.04$ echo -n "`hostname`: "; (pkg_info | grep linux_base) ; java -version
heinz.jollem.com: linux_base-6.1 The base set of packages needed in Linux mode
java version "1.3.0_02"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.0_02)
Java HotSpot(TM) Client VM (build 1.3.0_02, interpreted mode)

But on the second I do:

bash-2.04$ echo -n "`hostname`: "; (pkg_info | grep linux_base) ; java -version
catbert.jollem.com: linux_base-6.1 The base set of packages needed in Linux mode
java version "1.3.0_02"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.0_02)
Java HotSpot(TM) Client VM (build 1.3.0_02, interpreted mode)
Java HotSpot(TM) Client VM warning: cannot uninstall alt signal stack

Perhaps it is the kernel version. I have recently recompiled the kernel on the
first machine (heinz), but it's been a while since I recompiled the kernel on
the second (catbert).

Anyway, I will try deinstalling and reinstalling linux_base and try again
after that.

I have just reinstalled the emulators/linux_base port on both systems, and
then ran java -version again, but the results are the same as before. Seems
it's not a linux_base issue.

You have altered jre/lib/jvm.cfg right? The order it should try JVMs
needs to be:

-classic
-client
-hotspot
-server

Replying to my own mail...

I'll submit a patch for the port to do this tomorrow if noone beats me
to it. This is certainly how the port needs to be configured, at least
for now.

Hi Greg,

Quote:> You have altered jre/lib/jvm.cfg right? The order it should try JVMs

Nope, I haven't modified anything, I just installed the port, nothing else.
But it seems the JVM is running in interpreted mode anyway:

Quote:> > Java HotSpot(TM) Client VM (build 1.3.0_02, interpreted mode)

It *does* say "HotSpot" though. Hmm... This is confusing me. Isn't
"interpreted mode" a different mode than "hotspot client mode" ?

Anyway, I tried running a real-world Swing application (BugSeeker for Java 2,
v1.0.2), on the box where I didn't get the error message (heinz) and it runs
just fine. No problemo. I can't say it's blazing fast, but it's not slow
either.

Just a minute. It seems HotSpot Client VM is actually working on my system,
isn't it? Perhaps the latest version of -STABLE solves the problem we were
having with HotSpot in the past?

Not likely. Last I heard it requires kernel threads which are still in
development on FreeBSD 5.0.

Sorry I was 1/2 asleep when I wrote that... I was talking about kernel
patches, not in the port.

Here's a bit from the commit email:

Modified files: (Branch: RELENG_4)

Log:
MFC: Linux signal handling fixes from current. This should improve
emulation of signal intensive Linux apps (such as Java). This allows an
older version of the IBM JDK to run on -stable and gets rid of the
"cannot uninstall sigaltstack" message from the Sun Linux JDK 1.3

Do I read this correctly? Does it mean that 4.2-STABLE after February
21st should run IBM JDK 1.1.8?
Can anyone confirm this? (i.e. success running jdk?)

Sounds like somebody will be doing build world today ;)

Ok, so maybe the port doesn't need patches...but thats definitely the
message Ernst was getting. Whne was your 4.2-STABLE system last rebuilt
Ernst? If its before this commit, you prolly need to rebuild and try
again.

The system that didn't give an error message:

FreeBSD heinz.jollem.com 4.2-STABLE FreeBSD 4.2-STABLE #8:
Sat Mar 3 16:58:33 CET 2001

The system that did give an error message:

FreeBSD catbert.jollem.com 4.2-STABLE FreeBSD 4.2-STABLE #21:
Sat Jan 2 02:11:48 CET 1999

Gonna rebuild my kernel and make world again, and then I'll let the list know
:)
