It sure says mor than just "error startign the modern compiler". What is
the actual error?

The value attribute takes the string you provide and turns it into a
single command line argument. This is not what javac expects. Either use
separate <compilerarg> elements per argument or use the line attribute
as in
<compilerarg line="--patch-module java.base=src -d
./src/main/java/jdk/compiler/DocTree.java" />
which splits the attribute's value into separate arguments on spaces.
