transient java object instance from jvm through jni?

Hello, All

Sometimes I want manage the memory take by object instance,

for example, If I want to design a cache which cache a huge number object.

Then, there may two problems:

1, May occur OutOfMemory error.

2, I want like to manually reclaim the memory take by the cached object,

not by gc, because it may take a little time to check the reference for gc.

Just as you know, there is keywordtransient for serialization.

I want know if some same mechanism for object instance creating or release, managing memory by jni, or by some other way?
