- * "find_java.exe", for Windows only.
- * Tries to find a Java binary in a variety of places and prints the
- * first one found on STDOUT and returns 0.
- *
- * If not found, returns error 1 with no message
- * (unless ANDROID_SDKMAN_DEBUG or -d if set, in which case there's a message on STDERR).
- *
- * Implementation details:
- * - We don't have access to ATL or MFC.
- * - We don't want to pull in things like STL.
- * - No Unicode/MBCS support for now.
- *
- * TODO for later version:
- * - provide an env variable to let users override which version is being used.
- * - if there's more than one java.exe found, enumerate them all.
- * - and in that case take the one with the highest Java version number.
- * - since that operation is expensive, do it only once and cache the result
- * in a temp file. If the temp file is not found or the java binary no
- * longer exists, re-run the enumaration.
