#KT-2047 Fixed

modified the JS compiler so that it can have definitions and library sources specified or discovered on the classpath; so for example we can then discover the kotlin standard library kotlin that needs to be compiled; plus the JS library definitions (which map to the kotlin-lib.js file)

scala-library descriptors does not fit in memory, so resolve it in chunks

BTW scala-library it is resolved fine
