eclipse-wtp is currently affected by a build failure caused by the recent jflex upgrade, so it seems to me that the build does process the grammars.
Regarding the rsc files, there are: org.eclipse.wst.jsdt.core/src/org/eclipse/wst/jsdt/internal/compiler/parser/part14.rsc org.eclipse.wst.jsdt.core/src/org/eclipse/wst/jsdt/internal/compiler/parser/part1.rsc org.eclipse.wst.jsdt.core/src/org/eclipse/wst/jsdt/internal/compiler/parser/part2.rsc org.eclipse.wst.jsdt.core/src/org/eclipse/wst/jsdt/internal/compiler/parser/start1.rsc org.eclipse.wst.jsdt.core/src/org/eclipse/wst/jsdt/internal/compiler/parser/start2.rsc I don't know what they are used for, but a quick hex dump seems to indicate these files are mostly empty: hexdump -C org.eclipse.wst.jsdt.core/src/org/eclipse/wst/jsdt/internal/compiler/parser/*.rsc 00000000 ff ff ff ff 3f ff ff ff ff ff ff ff ff ff ff ff |....?...........| 00000010 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................| 00000020 ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff |................| * 00000040 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................| * 00002000 ff ff ff ff ff ff ff ff 00 00 00 00 3f ff 3f ff |............?.?.| 00002010 ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff |................| 00002020 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................| * 00002060 ff ff 00 00 7f ff ff ff 00 00 00 00 00 00 07 ff |................| 00002070 00 00 00 00 3f ff ff ff 00 00 00 00 00 00 00 00 |....?...........| 00002080 ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff |................| 00002090 00 00 03 ff 3f ff ff ff 00 00 00 00 00 00 00 00 |....?...........| 000020a0 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................| * 00002100 ff ff ff ff ff ff fd 3f 00 00 00 00 00 00 00 00 |.......?........| 00002110 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................| * 00003a20 00 00 00 00 00 00 00 00 ff ff e3 e0 00 00 00 00 |................| 00003a30 00 00 3c 00 00 00 0f e7 00 00 00 00 00 00 00 00 |..<.............| 00003a40 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................| * 00003a80 ff ff ff ff ff ff ff ff ff ff ff ff ff df ff ff |................| 00003a90 ff ff ff ff df ff ff ff ff ff ff ff ff ff ff ef |................| 00003aa0 ff ff ff ff df df e7 bf ff ff ff ff ff fd fc 5f |..............._| 00003ab0 ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff |................| * 00003ad0 ff ff ff ff ff ff ff ff ff ff ff ff f7 ff ff fd |................| 00003ae0 ff ff ff ff ff df ff ff ff ff ff ff ff ff 7f ff |................| 00003af0 ff ff ff ff ff ff fd ff ff ff ff ff ff ff c3 f7 |................| 00003b00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................| * 00004000 ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff |................| * 000054d0 ff ff ff ff ff ff ff ff 00 00 00 00 00 7f ff ff |................| 000054e0 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................| * 00005f00 ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff |................| * 00005f40 00 00 00 00 3f ff ff ff 00 00 00 00 00 00 00 00 |....?...........| 00005f50 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................| * 00006000 ff ff ff ff ff ff ff ff 00 00 00 00 3f ff 3f ff |............?.?.| 00006010 ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff |................| 00006020 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................| * 00006060 ff ff 00 00 7f ff ff ff 00 00 00 00 00 00 07 ff |................| 00006070 00 00 00 00 3f ff ff ff 00 00 00 00 00 00 00 00 |....?...........| 00006080 ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff |................| 00006090 00 00 00 00 3f ff ff ff 00 00 00 00 00 00 00 00 |....?...........| 000060a0 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................| * 00006100 ff ff ff ff ff ff fd 3f 00 00 00 00 00 00 00 00 |.......?........| 00006110 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................| * 00007a80 ff ff ff ff ff ff ff ff ff ff ff ff ff df ff ff |................| 00007a90 ff ff ff ff df ff ff ff ff ff ff ff ff ff ff ef |................| 00007aa0 ff ff ff ff df df e7 bf ff ff ff ff ff fd fc 5f |..............._| 00007ab0 ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff |................| * 00007ad0 ff ff ff ff ff ff ff ff ff ff ff ff f7 ff ff fd |................| 00007ae0 ff ff ff ff ff df ff ff ff ff ff ff ff ff 7f ff |................| 00007af0 ff ff ff ff ff ff fd ff 00 00 00 00 00 00 03 f7 |................| 00007b00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................| * 00008000 ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff |................| * 000094d0 ff ff ff ff ff ff ff ff 00 00 00 00 00 7f ff ff |................| 000094e0 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................| * 00009f00 ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff |................| * 00009f40 00 00 00 00 3f ff ff ff 00 00 00 00 00 00 00 00 |....?...........| 00009f50 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................| * 0000a000 Maybe these files are just stubs used by the compiler to create real resources files?
