Java Programming - Program Crash using -Xprof
My program runs without problems but when
I tried to use the -Xprof flag when running my program
it crashes consistently.
As soon as the program starts and the GUI displays
the entire GUI is unresponsive.
Since none of the menus or window buttons work there isnt
much I can do. After a few moments Windows says its
unresponsive and shuts it down.
I dont have any experience reading (intrepretting) the -Xprof output
but here it is. Im assuming the 2nd to last line implies that some
Threads are being horribly blocked?
