私はこの問題を持っています：のJavaのOutOfMemoryError：メモリ使用量が高すぎる：physicalBytes> maxPhysicalBytes javacppポインタメモリ解放（）
java.lang.OutOfMemoryErrorを：物理メモリの使用率が高すぎる：physicalBytes = 1G> maxPhysicalBytes = org.bytedeco.javacpp.Pointer.deallocatorで1G（Pointer.java:562）
長いPointer.physicalBytesは、我々はすべての単一のポインタオブジェクトの割り当てを解除し、GCを呼び出す場合にも増加している - 私は、JVMのヒープサイズを監視してきたし、それは制御下にあり、決して20％を越える使用は決して解約されないが、何らかの理由で情報（本物）がPに渡されていないことを意味する（減少れることは決してありません）oniter.physicalBytes、それはこれが（https://github.com/bytedeco/javacpp-presets/issues/423）数週間前に修正されましたが、私はまだであっても、この問題が生じていますようにPointer.maxPhysicalBytes
の値が見える達したとき、それは誤ってエラーをスローしますJavaCPPの最新バージョン（1.3.3）
