Re: Java Thread Dump in Bash
Ha, now I saw a thread dump in bash console. Unfortunately it kills
immediately the java app. In RXVT I see a single new line with "i"
printed and the app is killed.
My $CYGWIN is "nontsec nosmbntsec". Java is run from SDK as you do. My
cygwin is latest, too (just updated again).

Unfortunately neither Ctrl-Break nor Ctrl-Scroll produce a thread dump
not in pure bash and not in RXVT for me. I'm using latest cygwin and
tried JDK 1.4.2_02 and 1.5.0 beta.
Also the java applications I tried do not read from standard input.
What versions (cygwin/java) do you use.
Cygwin: Latest "kernel" and latest version of all packages.
Java: Latest (specifically, 1.4.2_03); If it might matter, I generally
use the "java" and "javac" commands from the SDK bin, not the "jre" bin.
That's the directory that includes the compiler and related development
tools, where as the jre bin has only the JVM and other runtime resources.
By "pure BASH" I take it you mean BASH in a console window, in contrast
to an RXVT window. I do _not_ use the "tty" option in the CYGWIN
environment variable. Do you?
Is it worth to send my cygcheck output attached? Should I really
expect Ctrl-Break to work - this would be great?
I expect it to work because it does work for me...
Cygcheck output isn't anything I can use for any purpose I can think of
in resolving this discrepancy between how your system and mine behave.

Frank-Michael,
CTRL-BREAK produces a thread-dump using the latest Sun JVM on my
system when launched from BASH. However, if the program is reading
standard input from the unredirected console, it receives an
end-of-file indication on that stream as well.

Searching the mailing list archive I found that there is an old
thread from Dec 2000 which exactly describes my problem:
http://sources.redhat.com/ml/cygwin/2000-12/msg00490.html
In short: Using Ctrl-Scroll does not cause a Java program to dump
threads as it does in cmd.exe. Unfortunately the thread ended up
with some personal strife.
I understand that the signal problem could be by design. But now (3
years later) maybe there are news about this issue? Has someone a
way to work around this problem?
