Hey guys, I'm having a problem with my Minecraft that I've never seen before. I enter into my account in the launcher and click play, wait for the version to load, and boom. I get this.

where options include:
-d32 use a 32-bit data model if available
-d64 use a 64-bit data model if available
-server to select the "server" VM
The default VM is server.

-cp <class search path of directories and zip/jar files>

and ZIP archives to search for class files.

Java HotSpot(TM) 64-Bit Server VM warning: Using incremental CMS is deprecated and will likely be removed in a future release

I've never seen this error report in any of the forums, and none of my friends have ever encountered it either. I tried running it on 1.8.9, 1.8.8, 1.7.10, and 1.7.2, all with the same results, online and offline.

I'm running minecraft on an ASUS ROG G Series with an I7-4720HQ processor, 16gb of RAM, a 64- bit operating system, and have tried running it off both my Intel HD Graphics 4600 graphics card and my NVIDIA GEFORCE GTX 960M graphics card with no avail. I am running Java 8 Update 65 right now. Please help!

Edit: I have tried uninstalling and reinstalling several times with no apparent change

Note: Updated Java to 8u71 but no change still

Grimalq has had success telling people to reconfigure their JVM line to use java.exe instead of javaw.exe

Open profile editor, check Executable field. Change "javaw.exe" to "java.exe", don't touch the rest of the text.

I don't understand why this problem occurs in the first place though. javaw should work, and the fact that it doesn't is the sign that something is wrong somewhere. I wonder whether something has modified the parameters being passed in or that javaw.exe has been replaced (either of these surreptitiously as some kind of malware attack).

In fact I just did an experiment on my system, java.exe spits out this kind of message to the console. javaw.exe shouldn't ever spit this out because it isn't supposed to have a console. So it's like they have been reversed.

weird.

Thanks! I did what you said and for some odd reason it worked lol. I really appreciate your help!
