Start by reproducing the package-name parsing error using the attached shade-issue-MSHADE-317.zip and the relocation configuration in the report. Trace how the shadedPattern containing the original pattern is parsed, then verify that the generated shaded package name matches the configured com.alibaba.arthas.deps.org.objectweb.asm prefix.
