Start with src/main/java/org/apache/maven/plugins/shade/relocation/SimpleRelocator.java, especially RX_ENDS_WITH_DOT_SLASH_SPACE and RX_ENDS_WITH_JAVA_KEYWORD. Review the affected source patterns and then run the relocation cases in src/test/java/org/apache/maven/plugins/shade/relocation/SimpleRelocatorTest.java. Done means shaded sources preserve the listed operators and Java keywords while relocating referenced names correctly.
