A Java OutofMemoryError occurs if the program attempts to use more heap space than is available. Among other causes, this error may result from
- a memory leak (see MSC05 MSC04-J. Do not leak memory)
- an infinite loop
- limited amounts of default heap memory available
- incorrect implementation of common data structures (hash tables, vectors and so on)
- unbound deserialization
- writing a large number of objects to an
ObjectOutputStream(see SER10-J. Avoid memory and resource leaks during serialization) - creating a large number of threads
- uncompressing a file (see IDS04-J. Limit the size of files passed to ZipInputStream)
