Thanks @coleenp and @lmesnik for the review.
Only in vmTestbase/metaspace/stressHierarchy/common/generateHierarchy/GenerateHierarchyHelper.java, the batch compile is used. Even there, we could replace it with iteration of single compiles.
I will remove all the instances of batch compile and keep the InMemoryJavaCompiler clean and simple.
