Picked up JAVA_TOOL_OPTIONS: -Xmx128m

I get this error now when compiling and or running java It broke and I know because I am using the built in console workspace I probably cannot fix this and Treehouse needs to? Let me know! I am currently downloading the JDK and will do this on my laptop, but I like using workspaces.

This isn't an error, it's an informational message from the JVM about an option we enabled in Workspaces to help prevent the JVM from snagging too much RAM and killing user processes. You can just ignore that line in the output.

Line is ignored, but program will not compile, thus program will not run.

hey john,

that's exactly right. there's no problem with changing that, but be aware that if the process consumes too much memory, it will be killed by the operating system's OOM-killer. we set the 128M as a sane default to prevent this, and it's more than adequate for all of the tasks we have students working on as part of their coursework.

cheers,

nathan

I came across an error like this when trying to mod Minecraft (and proud of it)

It is to do with how much memory Java is allocated. The Xmx-128 has to do with the heap space.

I highly recommend Treehouse's workspace and I hope I am not breaching any terms and conditions with this fix: the following should help you to increase the java heap space.

How do you get it to compile in Treehouse Workspaces when you're receiving Picked up JAVA_TOOL_OPTIONS: - Xmx128m and Picked up JAVA_OPTIONS: - Xmx128m?
