How to avoid Memory leak issue in Java What is Memory Leak? Memory leak is a bug that mainly occurs when a program does not release the memory it has obtained for temporary use. In other words we can say it is the condition where the available computer memory reduces gradually there by ...
4.3. Use Reference Objects to Avoid Memory Leaks We can also resort to reference objects in Java that come built-in with thejava.lang.refpackage to deal with memory leaks. Using thejava.lang.refpackage, instead of directly referencing objects, we use special references to objects that allow t...
It is recommended to follow the coding practices suggested in the following documents to avoid memory leaks in your application. JDBC– Closing JDBC Objects JNDI– Closing the Context JMS– Releasing Object Resources Diagnosing out of memory errors and memory leaks BYRAMAKANTA· PUBLISHED JULY 29, ...
This is the memory that the JVM uses for its own internal operations. The amount of native memory heap that will be used by the JVM depends on the amount of code generated, threads created, memory used during GC for keeping java object information and temporary space used during code generat...

To deal with other cases when one wants to avoid nulls, different strategies may be used. One of these strategies is to use Optional type that can either be an empty object or a wrap of some value: Optional<String> optionalString = Optional.ofNullable(nullableString);if(optionalString.isPrese...
Apply proper synchronization (prefer atomics to locks, minimize critical sections) to avoid race conditions when calling into the native layer. Concurrency-unaware code will cause memory corruption and other state inconsistency issues in and around the shared data sections. JNI-6: Secure library ...
We also identify 13 recurring code transformations in the repair patches. Based on our findings, we draw a variety of implications on how developers can avoid, detect, isolate and repair leak-related bugs.doi:10.1007/s10664-019-09731-8Ghanavati, Mohammadreza...
focus on writing code without worrying about memory management, making Java a popular choice for building complex and large-scale applications. However, understanding how Garbage Collection works is essential for Java developers to optimize their code's performance and avoid common memory-related errors...
they are released only to avoid an out-of-memory error. In this respect, they differ greatly fromweak references, which never prevent the garbage collection of an object. Soft References are very popular in cache implementations for precisely this reason. The cache developer assumes, correctly, ...
