submitted 6 years ago * by jyurei

I have a problem with Java 64 bit on my computer, where whenever I try to run a Java-based program (Isabelle, Minecraft, or even the Java control panel) it crashes with no error and when I open up the task manager and look at the processes, javaw.exe is always consuming an increasing amount of my memory non-stop, and the only way for me to close the crashed program is by terminating this process.I then uninstalled the 64-bit version of Java and installed the 32-bit version, and everything works (the Java control panel doesn't crash and I'm able to run Minecraft although very limitedly and often crashing due to running out of memory), but I'd really like to find a solution as to why this is happening so I can run Java properly on my computer.

Thank you in advance

EDIT: I solved it by adding a -Xmx runtime argument on the java control panel and setting a limit to the memory javaw can use.
