Relax import constraints for Automation Scripting

It's now possible to allow specific Java classes to be used via Automation Scripting, by default we add: java.util.ArrayList java.util.Arrays java.util.Collections java.util.UUID org.nuxeo.runtime.transaction.TransactionHelper org.nuxeo.ecm.core.api.Blobs org.nuxeo.ecm.core.api.impl.blob.StringBlob org.nuxeo.ecm.core.api.impl.blob.JSONBlob Other classes can be added, and previously-allowed ones denied, through: <require> org.nuxeo.automation.scripting.classfilter </require> <extension target= "org.nuxeo.automation.scripting.internals.AutomationScriptingComponent" point= "classFilter" > <classFilter> <allow> com.example.MyClass </allow> <allow> com.example.MyOtherClass </allow> <deny> org.nuxeo.runtime.transaction.TransactionHelper </deny> </classFilter> </extension> One can use <deny>*</deny> to disallow all previously-allowed classes. The default contribution now allows scripting code like: function run(input, params) { var uuid = java.util.UUID.randomUUID().toString(); return org.nuxeo.ecm.core.api.Blobs.createJSONBlob( "{\" uuid\ ": \" " + uuid + " \ "}" ); }
