Error in scene - OutOfMemoryError

While using the netbeans based SDK and browing through the community assets in the assetpackbrower I always eventually get this error

“Error in scene! java.lang.OutOfMemoryError: Direct buffer memory”

after some googling people are suggesting it’s because the java VM has a built in memory limit of 64 megabytes. I tried clicking around in the jmonkey installation files for some kind of config setting where I could change this, but I couldn’t find anything…

is there a way to up the memory limit for the jmonkey sdk? and/or is there a way to unload models after previewing them in the sdk so they dont just accumulate and waste my available memory.

as of now the only way I know to fix this is to restart the program. which is getting annoying fast.
