remote debugging problem using jdb and 1.3.0
I know I've been able to use JDB in the past to remotely debug an application, but for some reason I can't get it to work with 1.3.0-C.
I've set up a very simple 'toy' Swing application as a test.
I have copied this example almost directly from the Sun tool docs:
=======================
set path=d:\batch;d:\jdk1.3\bin
java -classic -Xdebug -Xnoagent -Djava.compiler=NONE -Xrunjdwp:transport=dt_shmem,address=jdbconn,server=y,suspend=n D:\MyDir\MySwingApplication
=======================
I try to connect using this:
=======================
set path=d:\batch;d:\jdk1.3\bin
jdb -attach jdbconn
=======================
But I get a NullPointerException when it tries to connect:
Internal exception: java.lang.NullPointerException
at com.sun.tools.example.debug.tty.VMConnection.open(VMConnection.java:138)
at com.sun.tools.example.debug.tty.Env.init(Env.java:68)
at com.sun.tools.example.debug.tty.TTY.main(TTY.java:923)
It doesn't seem to matter whether I use the classic or the HotSpot VM. Both give the same error.
Any thoughts?
