             Summary: Do not compile exec model classes in RAM
                 Key: DROOLS-5113
                 URL: https://issues.redhat.com/browse/DROOLS-5113
             Project: Drools
          Issue Type: Enhancement
          Components: executable model
            Reporter: Luca Molteni
            Assignee: Luca Molteni


Currently executable model classes are compiled in RAM

	at org.drools.compiler.commons.jci.compilers.AbstractJavaCompiler.compile(AbstractJavaCompiler.java:49)
	at org.drools.modelcompiler.builder.CanonicalModelKieProject.writeProjectOutput(CanonicalModelKieProject.java:81)
	at org.drools.compiler.kie.builder.impl.KieBuilderImpl.buildKieProject(KieBuilderImpl.java:285)
	at org.drools.compiler.kie.builder.impl.KieBuilderImpl.buildAll(KieBuilderImpl.java:247)
	at org.drools.compiler.kie.builder.impl.KieBuilderImpl.buildAll(KieBuilderImpl.java:204)

This kie-benchmark fails when running with 10000 rules with the exec model and the lambda externalization activated
