Could not reserve enough space for object heap

Run the JVM with -XX:MaxHeapSize=512m (or any big number as you need) (or -Xmx512m for short)


This can also be caused by setting something too large on a 32-bit HotSpot vm, for example:

-Xms1536m -Xmx1536m

where this might/would work:

-Xms1336m -Xmx1336m

here is how to fix it:

  • Go to Start->Control Panel->System->Advanced(tab)->Environment Variables->System

    Variables->New: Variable name: _JAVA_OPTIONS Variable value: -Xmx512M Variable name: Path
    Variable value: %PATH%;C:\Program Files\Java\jre6\bin;F:\JDK\bin;

Change this to your appropriate path.
