Removed HandleWeakReference and made ObjectHandlesImpl to be a storage class
In JNIGlobalHandles created 2 instances of ObjectHandlesImpl (one for strong and one for weak hadles). I divided the total global handels range into two halfs at bit 62. Bit 62 is 0 for strong global handles and 1 for weak global handles. Therefore a validation tag is redused from 32 bit to 31 bit

Hello Dr. @christianhaeubl, per our discussion, I've opened this PR with the strong/weak handle refactoring. I'd appreciate your review when you have a moment. Thank you! |
resolved some grammar mistakes and updated the split point in JNIGlobalHandles and replaced it from bit 62 to bit 30, because it did not fit in the global handles range

Delected the duplicated variables in JNIGlobalHandles

In ObjectHandlesImpl all methods specific to weak handles (like createWeak, isWeak, and destroyWeak) were removed. It no longer knows the difference between a strong and a weak handle. Its only job is to store an object at a given index and retrieve it.
In JNIGlobalHandles the single ObjectHandlesImpl instance was replaced with two separate instances: strongGlobalHandles and weakGlobalHandles. The 64-bit global handle space was split into two distinct ranges (strong and weak) by using a bit flag (bit 62). Two new methods, encodeStrong and encodeWeak, were created to correctly place a handle's value into its designated range.
