What JVM config options does Eclipse insert into application? [message #1829732]

I have a java application which behaves differently when I launch it from Eclipse than when I launch it from a standalone jar file. For instance, running standalone it hangs (seems to be a out of memory error, but I'm not sure). If I run it the exact same way from eclipse it runs fine with no errors.
I'm just wondering how does Eclipse launch applications, does it insert hidden config options into the JVM (like -xmx or -xms)?

You can bring up the Properties for the node in the Debug view that represents your Java runtime to see the entire command invocation that launched it. Most of what's used in what you specified in your application's launch configuration.

Thanks for the answer.
You mean Run/Debug settings? I looked there, but I don't see any special settings. Everything is default.
Is there any other thing that Eclipse does that makes the java application run differently than when it runs from a standalone jar file?

No, not in the settings. When you Run or Debug something, the Debug view of the Debug perspective will show a tree node for that launched process. In the context menu of the child node, there is "Properties..." item and it bring up a dialog that includes things like the "Command Line:" which shows exactly how the process was launched. You can compare that to your manual command line launch.
