First off, are you running 32 bit or 64 bit Java? Not to mention Eclipse (Flash Builder). NB: Flash Builder is built on Eclipse. It looks like it is 32 bit (win32 mentioned in plugins line). This will give a maximum heap size of 2GB which you would not be able to set it to as there would not be any memory left to work with. Also, a DLL may have loaded into the memory area that the JVM wants to use for heap (The JVM needs a contiguous block of memory). Java is intelligent enough to give an error if you set initial(Xms) or maximum(Xmx) heap size too high.
