    Description

      Doing a minimalistic build ( for buildjdk, as part of cross-compilation process) with only parallelGC ( --with-jvm-features=-zgc,-compiler2,-epsilongc,-g1gc,-jfr,-jni-check,-jvmci,-jvmti,-shenandoahgc ) and getting this error:

      /jdk/src/hotspot/share/cds/filemap.cpp: In member function 'void FileMapHeader::populate(FileMapInfo*, size_t, size_t, size_t, size_t)':
      /jdk/src/hotspot/share/cds/filemap.cpp:258:32: error: 'G1CollectedHeap' has not been declared
        258 | address start = (address)G1CollectedHeap::heap()->reserved().start();

      cds is using G1 classes unconditionally
