How the RHPAM executes Java code inside a script task at runtime?

Issue

• I would know how the java code inside a script task is executed at runtime. Is compiled during the build time, after the bytecode is saved in the database as serialized blob or what else and after how is executed in the JVM. At the end, I would understand the steps above and the impact in terms of performance if is bad to have several script task with a lot of java code to be stored and executed in the process instance at runtime
