I've been having some random crashes of the JDK 1.1.5_v7. I believe
they're related to a window being disposed. This never happened with
sbb's JDK 1.1.3, but it happens maybe 15% of the time when I call
dispose on a Frame with 1.1.5.
Anything else I can do to pin this down? I'll try to see if I can
catch out the same bug in java_g, but since it's notdeterministic it's
hard to reproduce.
Here's the segfault from java:
SIGSEGV 11* segmentation violation
stackbase=0x4156b000, stackpointer=0x4156ac74
and the thread that looks to be the guilty party.
*current thread*

java.awt.Component.dispatchEventImpl(Component.java:1764)

java.awt.EventDispatchThread.run(EventDispatchThread.java:63)
And the relevant method in my application (line 70 of CreateAgentUI.java)
newAgentWindow is a Frame that was created by this same class - the
idea is that the CreateAgentUI class puts up a form (newAgentWindow),
waits for the user to click a button, then destroys the newAgentWindow.
public void createAgent() {
String remoteHost =
server.getServerDirectory().resolveToAddress(serverNameField.getText());
BaseAgent newAgent = null;
try {
newAgent = (BaseAgent)agentClass.newInstance();
} catch (Exception e) {
Debug.println(Debug.CRITICAL, "Agent could not be created: " + e);
return;
}
((MonitoringOneHost)newAgent).setHostToMonitor(remoteHost);
newAgent.launch(Global.localServer());
newAgentWindow.dispose(); // THIS IS LINE 70
}
