 It uses [JaQue](https://github.com/TrigerSoft/jaque) to build an expression tree for a lambda. The expression tree is then traversed and converted to a SQL statement. 
 
-Under the hood JaQue depends on the following system property:
-`jdk.internal.lambda.dumpProxyClasses`
+Under the hood, JaQue depends on the system property `jdk.internal.lambda.dumpProxyClasses`, if the lambda expression is not serialized:
 See [https://bugs.openjdk.java.net/browse/JDK-8023524](https://bugs.openjdk.java.net/browse/JDK-8023524).
 
 When the property is enabled, JVM generated classes for lambdas are saved to disk. JaQue then uses [ASM](http://asm.ow2.org/) to read the .class files and creates expression trees.
 
+Since the interface [`SqlPredicate<T>`](https://github.com/ajermakovics/lambda2sql/blob/master/src/main/java/lambda2sql/SqlPredicate.java) is automatically serialized, there is no need to set this property.
