Java - Excepcion: El explorador se cierra

Al entrar en una página en la que se tiene que cargar la máquina virtual se me cierra el navegador y se me genera un archivo de error en el escritorio, esto solo me pasa si tengo abierto el JBuilder(únicamente con tenerlo abierto)

el mensaje de error es el siguiente:

An unexpected exception has been detected in native code outside the VM.
Unexpected Signal : EXCEPTION_PRIV_INSTRUCTION (0xc0000096) occurred at PC=0x78023808
Function=[Unknown.]
Library=(N/A)

NOTE: We are unable to locate the function name symbol for the error
just occurred. Please refer to release documentation for possible
reason and solutions.
