Is this the same SymbolTable as classfile/symbolTable.cpp? that instance is assumed to be a singleton. Is this a different SymbolTable and can it have a different name (thought it was JfrSymbolTable). src/hotspot/share/jfr/support/jfrSymbolTable.hpp line 68: > 66: template <typename, typename, template<typename, typename> class, > typename, size_t> > 67: friend class HashTableHost; > 68: typedef HashTableHost<const Symbol*, traceid, ListEntry, > JfrSymbolTable> SymbolTable; Oh here it is. Since it's an enclosed type, can you rename it something simpler like Symbols and the other Strings? ------------- PR: https://git.openjdk.java.net/jdk/pull/4731
