Mocking HTTP Clients in AEM Projects

The first thing I learned as an AEM developer was mvn clean install -P autoInstallBundle. The second thing was how to debug a remote Java process.

Apache Sling JVM Performance Followup

In a comment on my previous post Apache Sling JVM Performance, Gil Tene made an insightful comment about the potential possibility of performance impact from speed from the underlying environment or other tests. To accommodate for this possibility, I re-ran the tests inside a loop, randomizing order of the JVM execution for each iteration 25 times. […]

Apache Sling JVM Performance Comparison

With the recent proliferation of Java Virtual Machine (JVM) implementations, it’s difficult to know which implementation is the best for your use case. While proprietary vendors generally prefer Oracle Java, there are several open source options with different approaches and capabilities.  Given how the implementations vary in some underlying technical specifics, the “correct” JVM implementation […]

Resource Streams in Apache Sling

Jörg Hoh recently wrote an interesting post on Content Architecture where he discussed how expensive JCR Queries could instead be replaced with targeted content structure traversals to allow finding relevant content without searching the whole AEM repository. Unfortunately, from a developer perspective, this means writing a fair amount of boilerplate code to traverse the AEM […]

Less is More: Write Clean Elegant Codes in AEM

A clean, elegant code base goes a long way. It helps developers read and modify the code, sets a good foundation for future development, reduces technical debts and maintenance overhead, makes code easier to unit test, follows best practices, and much more. This still holds true in the Adobe Experience Manager (AEM) world. However, many […]

2 Common Concurrency Pitfalls in AEM and How to Avoid Them

Concurrency issues are both disastrous and difficult to detect in non-production loads. They are more difficult to reproduce than most bugs because they specifically rely on multiple operations happening at/around the same time, which is difficult to reproduce in a development or local environment. Since concurrency bugs are hard to find and diagnose, we should […]
