DartEditor.exe and java exit code 1
I don't see anything wrong with your posted .ini contents, it could be that you are seeing https://bugs.eclipse.org/bugs/show_bug.cgi?id=188968
Essentially the -Xmx1024m might be too large and the jvm can't find a contiguous block of memory that large. Shared libraries might be loaded in the middle of the address space fragmentin the available memory).
By removing the .ini file, you get the default Xmx args which are much lower. You could try changing to -Xmx512m or -Xmx768m.
