Configure `LambdaIntrospector` cache size for an executable model build::::
You can configure the size of `LambdaIntrospector.methodFingerprintsMap` cache, which is used in an executable model build. The default size of the cache is `32`. When you configure smaller value for the cache size, it reduces memory usage. For example, you can configure system property `drools.lambda.introspector.cache.size` to `0` for minimum memory usage. Note that smaller cache size also slows down the build performance.
