def initialize(schema, options = nil)
  original_initialize(TebakoRuntime.extract_memfs(schema, wild: true), options)
  # ruby-jing captures `:default => DEFAULT_JAR` at class-load time —
  # before this adapter replaced the constant with the extracted host
  # path. Force the extracted path per-instance (a nil option hash
  # leaves @options empty, and the builder's stale default would win).
  @options[:jar] = DEFAULT_JAR
  # The mounted openjdk toolkit payload's java wins over PATH (the
  # memfs-binary exec path; the bare "java" keeps the PATH answer).
  @options[:java] = TebakoRuntime.mounted_exe("openjdk", "java")
end

Instance Method Details

#execute(options) ⇒ Object

The spawn shape, array form (the stock execute() backticks a shell string, which the tebako spawn hook deliberately skips; the mounted java only execs through the hook from an absolute-path array spawn).
