Files that control the amount of memory afforded to the JVM for JDeveloper upon startup, relative to the jdeveloper/ide/bin/ directory, include. java.lang.OutOfMemoryError; All Implemented Interfaces: Serializable. Thrown when the Java Virtual Machine cannot allocate an object because it is out of memory, and no more memory could be made available by the garbage collector.
