In that scenario, the garbage collector (GC) thread might not feel the urge to clean up JavaHeap memory, while the JNI Heap keeps on increasing till it goes out of memory.

This typically happens if you are making lots of heavy JNI calls, but the JavaHeap objects occupy little space. The Java Native Interface (JNI) Heap runs low on memory, even though the JavaHeap and the PermGen have memory. XX:MaxPermSize=256m(: PermGen space): PermGen space

Xmx (: Java heap space).: Java heap space JavaHeap space is low to create new objects.This exception mainly occurs due to possible reasons listed below: When the memory footprint hits the threshold, the JVM throws the exception. This can be either due to valid objects that are required to stay in Java heap memory, or because the programmer forgot to remove the reference to unwanted objects (typically known as 'memory leaks' in Java parlance).īelow are a few simple Java performance tuning tips which you can follow during your development process: The memory usage of the application is related to the number and size of live objects that are in the Java virtual machine (JVM) at any given point of time. Your application may not be responding well because it's spending too much time in cleaning up the garbage rather than running the necessary processes. You may be facing one of the issues listed below: The finally block is a key tool for preventing resource leaks In this blog, I am focusing specifically on Java heap and Java performance tuning. It may vary depending on your interpretation and experience. Java application performance has always been a mere buzzword until you face its real implications.
