What is a JAXB context?
The JAXBContext class provides the client’s entry point to the JAXB API. It provides an abstraction for managing the XML/Java binding information necessary to implement the JAXB binding framework operations: unmarshal, marshal and validate.
What is memory leak with example?
In computer science, a memory leak is a type of resource leak that occurs when a computer program incorrectly manages memory allocations in a way that memory which is no longer needed is not released. A memory leak may also happen when an object is stored in memory but cannot be accessed by the running code.
What is a memory leak vulnerability?
Description. A memory leak is an unintentional form of memory consumption whereby the developer fails to free an allocated block of memory when no longer needed. The consequences of such an issue depend on the application itself.
Is marshalling the same as serialization?
Marshaling and serialization are loosely synonymous in the context of remote procedure call, but semantically different as a matter of intent. In particular, marshaling is about getting parameters from here to there, while serialization is about copying structured data to or from a primitive form such as a byte stream.
How do you prevent memory leaks?
Use Heap Memory Effectively
- Copy objects instead of passing references. Pass a reference only if the object is huge and a copy operation is expensive.
- Avoid object mutations as much as possible.
- Avoid creating multiple references to the same object.
- Use short-lived variables.
- Avoid creating huge object trees.
How can we avoid memory leaks?
Is JAXB part of JDK?

Is there a memory leak in jaxbcontext.newinstance?
JAXBContext.newInstance memory leak. After a recent deployment in system test, one of our servlets was getting hit much harder than usual and we noticed memory started climbing and weblogic would eventually die.
Why is there a memory leak in Java?
My intern, I was very proud, discovered the source of the memory leak. Whenever a request comes in, this line gets called: For some reason, the object never gets garbage collected. Once we made it static and moved where we initialized it, our memory leak went away.
Is the JAXBContext method thread safe in Java?
The good news is that JAXBContext is thread-safe and should only be created once and re-used. Reusing the JAXBContext also appears to be solving your memory leak. Yes, it’s a leak. It will load the class “ruby.oracle_servlet.schemas”, every time this method is called.
