Fix memory leaks in Java production applications in 5 steps
05/07/2013 at 10:53:58
Adding more memory to your JVMs (Java Virtual Machines) might be a temporary solution to fixing memory leaks in Java applications, but it for sure won’t fix the root cause of the issue. Instead of crashing once per day it may just crash every other day. “Preventive” restarts are also just another desperate measure to minimize downtime – but – let’s be frank: this is not how production issues should be solved. Based on a real life scenario we recently went through we discuss the 5 Steps it takes from analyzing to fixing memory issues in production environments.

Java.next: Common ground in Groovy, Scala, and Clojure, Part 3
The last of three installments about commonalities among Clojure, Scala, and Groovy investigates how these languages handle exceptions, expressions, and null -- all problem areas for the Java language. Each of the Java.next languages addresses the shortcomings of the Java language through a unique implementation that highlights that language's characteristics.

Java.next: Common ground in Groovy, Scala, and Clojure, Part 1
The Java.next languages (Groovy, Scala, and Clojure) have more commonalities than differences, converging toward common ground in many of their features and conveniences. This installment explores how they each address a longstanding deficiency in the Java language -- the inability to overload operators. It also discusses the related concepts of associativity and precedence.

Java.next: Common ground in Groovy, Scala, and Clojure, Part 2
Common complaints about the Java language concern excessive ceremony for simple tasks and defaults that are sometimes confusing. All three of the Java.next languages take more sensible approaches in those areas. This installment of Java.next shows how Groovy, Scala, and Clojure smooth out the Java language's rough edges.
