Research direction

Start with the stack trace and inspect com.taobao.profile.instrument.ProfTransformer.transform at ProfTransformer.java:55, then trace how ASM ClassReader receives class data during startup. Reproduce the tprofiler-master startup failure and determine which input triggers the array-bounds exception; done means startup completes without this exception.
