Start at com.alipay.euler.andfix.patch.Patch.init(Patch.java:75) and follow PatchManager.addPatch and initPatchs from the reported stack trace. Inspect how the patch file reaches JarFile and verify whether the patch is empty or truncated; done means identifying the cause of the zero-length archive and confirming valid patch loading without this exception.
