Java Agents In this final lesson we are going to talk about Java agents, a real black magic for regular Java developers out there. Java agents are able to “intrude” into the execution of Java applications running on the JVM at runtime by performing the direct modifications of the bytecode. Java agents are extremely as powerful as dangerous: they can do mostly everything however if something goes wrong, they can easily crash the JVM.
In this final lesson, we will discuss how to Analysis. Analysis, in Lucene, is the process of converting field text into its most fundamental indexed representation, terms.
