if defined ES_JAVA_HOME (
  set JAVA="%ES_JAVA_HOME%\bin\java.exe"
  set JAVA_TYPE=ES_JAVA_HOME
) else if defined JAVA_HOME (
  rem fallback to JAVA_HOME
  echo "warning: usage of JAVA_HOME is deprecated, use ES_JAVA_HOME" >&2
  set JAVA="%JAVA_HOME%\bin\java.exe"
  set "ES_JAVA_HOME=%JAVA_HOME%"
  set JAVA_TYPE=JAVA_HOME
) else (
  rem use the bundled JDK (default)
  set JAVA="%ES_HOME%\jdk\bin\java.exe"
  set "ES_JAVA_HOME=%ES_HOME%\jdk"
  set JAVA_TYPE=bundled JDK
)

set JAVA="%ES_HOME%\jdk\bin\java.exe" 
set JAVA_HOME="%ES_HOME%\jdk"
