Seeing this is surprising since JDK-8354724: "Methods in java.io.Reader to read all characters and all lines" which added these methods was add in JDK 25 build _26_ while, presumably many other changes from build 26 are already present in the symbol file.

src/jdk.compiler/share/data/symbols/java.base-P.sym.txt line 137:

Presumably this is from JDK-8353686: "Optimize Math.cbrt for x86 64 bit platforms", which was also present in build 26.
