[MCL-1440] Ignores -Xmx tag at will / Injects -Xmx512 at the end of JVM arguments

Crashes with :

Client> Error occurred during initialization of VM
Client> Incompatible minimum and maximum heap sizes specified
Client> Picked up _JAVA_OPTIONS: -Xmx512M
Game ended with bad state (exit code 1)
Ignoring visibility rule and showing launcher due to a game crash

Seems to appear that the Xms tag is read but the Xmx tag is ignored, meaning that Xms > Xmx, which results in the crash.

Reasons to believe this:

"Client> Picked up _JAVA_OPTIONS: -Xmx512M" in log suggests that it is forced to run with 512 MB of RAM.
Running with JVM args "-Xmx2048M -Xms512M" works fine but with "-Xmx2048M -Xms513M" still crashes.

Please attach the complete output of the "Crash Report" tab of the launcher.

David Goldman 2013-08-08T17:11:47Z

There is no "Crash Report". Minecraft does not launch - initialization fails in the construction of the VM. I've posted everything that there is to know - filtered out the noise from the regular log.

Talven81 2013-08-08T17:18:27Z

Then I misunderstood what you originally posted...

Please attach the complete output of the "Development console" tab of the launcher.

Click the text, press CTRL-A, then CTRL-C, and paste with CTRL-V in the ticket.
If the launcher closes after game start, please edit your profile and select "Launcher visibility" then, "Hide launcher and reopen" or "Keep the launcher open"

David Goldman 2013-08-08T17:23:50Z

Attached log as file. Also, very strangely, if I restart, it sometimes works on the first try (not always). But even if it works on the first run, it never works again.

You set the maximum mem size to 512M via _JAVA_OPTIONS and the minimum mem size to 1024M via command line. That's conflicting.
Simply remove _JAVA_OPTIONS from your environment or set it appropriately.

How do I remove it? I don't see it in System Environmental Variables..

kumasasa 2013-08-08T19:18:33Z

Hm. Do you see that variable when opening a shell with cmd and typing set there ?
If yes, then something will set that outside of the windows system environment thing.
If no - I dunno...
In either case go to the help chat at http://webchat.esper.net/?channels=minecrafthelp or irc://irc.esper.net/minecrafthelp and refer to this ticket.

David Goldman 2013-08-08T19:29:42Z

Nope. Nothing is there..

From reading online, it appears that just doing java -version should print out the _JAVA_OPTIONS, but it doesn't.

C:\Users\David>java -version
java version "1.7.0_25"
Java(TM) SE Runtime Environment (build 1.7.0_25-b17)
Java HotSpot(TM) 64-Bit Server VM (build 23.25-b01, mixed mode)

If I set the environmental variable, it appends it to the -Xmx value. Like I said before, it sometimes works once on start up. This leads me to believe some application is setting it?

kumasasa 2013-08-08T19:42:59Z

Set it to -Xmx2G then it won't conflict with -Xms1G

David Goldman 2013-08-08T19:52:14Z

That works but then it over-powers everything, even programs in eclipse. Interestingly enough, eclipse does not see the "_JAVA_OPTIONS: -Xmx512M". Writing test programs now...

Still cannot reproduce this default _JAVA_OPTIONS. Not sure what's going on. Going to try what Minecraft does to launch the game now, see if that affects it.

David Goldman 2013-08-08T20:44:22Z

I cannot reproduce this _JAVA_OPTIONS setting. I believe this is indeed a bug with the Minecraft Launcher, not my computer.

EDIT: Actually, moving my class files to the ".minecraft" folder reproduces this problem. And once you start having the problem, the problem moves everywhere - not just the ".minecraft" folder.

EDIT: Now it did it in eclipse too. No idea what's causing this. Going to try completely removing java and reinstalling.

kumasasa 2013-08-08T21:05:51Z

_JAVA_OPTIONS can be set via the Control Panel -> Java (but don't know where, since my Java control panel has nothing like options, but I only have installed the 64 bit JRE but not the 32 bit JRE)

David Goldman 2013-08-08T21:09:13Z

Don't see an option for _JAVA_OPTIONS. Also, 64 bit java does lack the integrated update feature (maybe it lacks that feature too)? Note that I don't have 32 bit java installed and it's still doing it.

kumasasa 2013-08-08T21:13:13Z

Out of ideas here. Go to the chat, those people are solving strange problems the whole day.

David Goldman 2013-08-08T22:20:02Z

No idea what the problem is. Just gonna stick to -Xmx2G for now.

Joshua Mack 2014-05-19T19:50:56Z

I'd hate to bring back an old report, but its still existent in the current version. I am constantly running out of memory, even with -Xmx2048M -Xms512M. I've tried everything posted in this post, and mine MCL-1575. I do think this is a bug with the launcher, as using the same arguments in a custom launcher like MultiMC works fine.

Joshua Mack 2014-05-20T00:12:55Z

I don't think it is because every other launcher works. Also notice this in the JVM flags when I run out of memory:

-XX:HeapDumpPath=MojangTricksIntelDriversForPerformance_javaw.exe_minecraft.exe.heapdump -Xmx2048M -Xms512M -Xmx512M

It's injecting -Xmx512M at the end there, even though my JVM Arguments are -Xmx2048M -Xms512M. That would explain why we can't raise the Minimum above 512M, because its setting the max to 512M. I've checked setting after setting and even reinstalled Windows with only java and minecraft, still no luck. It has to be a Minecraft Launcher issue.

Added full crash report, just in case.

Joshua Mack 2014-05-20T05:01:22Z

This is really strange. I can allocate fine if I use Minecraft.jar instead of Minecraft.exe. That's bizarre, but I'll go with it. :/

kumasasa 2014-05-20T05:49:24Z

Reopened.

It looks like the _JAVA_OPTIONS setting might be causing problems. To resolve, you need to remove this setting:

Press the Windows key (between Ctrl and Alt) and the Pause/Break key (at the top of the keyboard, above the arrow keys) at the same time.
A window should popup, click on 'Advanced system settings'.
Click on 'Environment Variables'.
Delete the _JAVA_OPTIONS entry.

If you have Razer Synapse installed for a Razer mouse and/or Keyboard,it will add a invisible _JAVA_OPTIONS variable to your environment variables. (It's a bug in the Razer Synapse.)

This was the problem for me.
If you have that software either uninstall it or add _JAVA_OPTIONS with the -Xmx flag you want.
