I had same problem and I was tired of it solving, this is very huge problem. Reason is you have to be known that Jcreator is working on x86 architecture, so you must install 32 bit
Java Version, and in the configuration of Jcreator,
you must choose the path of 32 bit version of Java as -->
(C:\Program Files (x86)\Java\jdk1.8.0_66 )
Any time you may get this error so make sure to check the path of Java in Config of Jcreator.
My problem solved, hope it will work.
