javafx - Getting EXCEPTION_ACCESS_VIOLATION with Java 8 if I load data over 2 GB -

i using latest java runtime 8 , have created application in javafx load images in canvas. if info size below 2gb application runs fine, if 1 mb on 2gb next error logged.

a fatal error has been detected java runtime environment: exception_access_violation (0xc0000005) @ pc=0x0000000053def51c, pid=5716, tid=10968 jre version: java(tm) se runtime environment (8.0_20-b26) (build 1.8.0_20-b26) java vm: java hotspot(tm) 64-bit server vm (25.20-b23 mixed mode windows-amd64 compressed oops) problematic frame: v [jvm.dll+0x21f51c] failed write core dump. minidumps not enabled default on client versions of windows error study file more info saved as: c:\users\105064864\documents\netbeansprojects\javafx3dapplication\hs_err_pid5716.log compiled method (nm) 51180 1220 n 0 sun.misc.unsafe::copymemory (native) total in heap [0x0000000002f4fb10,0x0000000002f4fe90] = 896 relocation [0x0000000002f4fc30,0x0000000002f4fc78] = 72 main code [0x0000000002f4fc80,0x0000000002f4fe90] = 528 if submit bug report, please visit: http://bugreport.sun.com/bugreport/crash.jsp

i have tried several options , nil works.

i using windows 7 , jre 8.0

my java , os both 64 bit.

i have tried on 8gb , 16gb rams.

i have set vm options (-xmx4g) allocated 4gb , above nil works.

is there limit imposed graphic card of machine on data? or there other setting apart -xmx4g can set explicitly allow on 2 gb of info loading?

with magic number beingness 2gb, first thing comes mind somewhere there's array beingness initiliazed hold whole data. since in java array index must of type int (reference: http://docs.oracle.com/javase/specs/jls/se8/html/jls-10.html#jls-10.4), maximum array length can integer.max_value (2147483647). assuming info loaded single byte array, 2147483647 bytes ~ 2gb maximum capacity. thus, possible trying allocate larger array application results in aforementioned exception.

the situation typically handled loading info in chunks , not storing in single byte array. however, far i've gathered isn't code actual physical reading storage. perhaps if mention utilize case application easier come higher level solution

java javafx 64bit
