What happens when Java runs out of heap space?
OutOfMemoryError is a runtime error in Java which occurs when the Java Virtual Machine (JVM) is unable to allocate an object due to insufficient space in the Java heap. The Java Garbage Collector (GC) cannot free up the space required for a new object, which causes a java. lang.
What is the maximum Java heap space?
The theoretical limit is 2^64 bytes, which is 16 exabytes (1 exabyte = 1024 petabytes, 1 petabyte = 1024 terabytes). However, most OS’s can’t handle that. For instance, Linux can only support 64 terabytes of data. Note: We don’t recommend you exceed 2 GB of in use JVM heap.
