[rules-users] MVEL and nested properties takes longer time to build working memory

Hi, I have rules that uses nested properties. There are more than thousands of such rules. Before using any nested properties, time to build working memory(from decision tables) was pretty fast. After using nested properties, rule compilation time increased by many folds and it is worse in environments where NAS is used instead of SCSI disks. Worst thing is I am not able to profile app using VisualVM as it gives error that 64k limit of instrumented methods exceeded. So took some thread dump using jstack and see that most often thread is doing class loading. This is performed by MVEL classes. On seeing this I used custom class loader in KnowledgeBuilder and printed all loaded classes. I do not see that MVEL is using custom class loader and is directly reading class using some other class loader.This class loading is taking pretty long time when using network disks. Is there any way to speed up rule compilation time when using nested properties.Is there anything like a hint to tell MVEL to load fields of an object directly from that class instead of searching it in entire classpath? I see something like "m:" in MVELDialectRuntimeData.getParserConfiguration(). Using Drools 5.30 Final and Decision tables. Thanks, Anto
