These are the only two missing `@since` in `java.compiler` and `jdk.javadoc`.
SNIPPET_PATH was added in JDK 18 [here][https://github.com/openjdk/jdk/commit/0fc47e99d20a1ee886df878f1302769bdd913aab#diff-8f73114f8b0d0d5229231541d5583382c8e8d33147e285f3d90ed8801ce9228bR192]
isBlockTag() was added [here][https://github.com/openjdk/jdk/commit/3c0e2b4e16d8fb2f96741bc8d4188aa47f58dd15#diff-3ee1b6e2a11b201a39ce3f2ac14ea9832900d8a3a581bf26577064173d0c9082R101]
Very simple fixes - There will be a bigger one for jdk.compiler
