I've started the VM with -Xmx64m and creation of *just 4* JFXPanel instances causes an OutOfMemoryError.

{code}
java.lang.OutOfMemoryError: Java heap space

This makes JFXPanel almost unusable in environments such as NetBeans Platform, e.g. opening many tabs with content displayed via JFX. Increasing Xmx is not really a solution - who knows how many tabs will be opened...
