dnl @synopsis AX_JAVAC_AND_JAVA
dnl @synopsis AX_CHECK_JAVA_CLASS(CLASSNAME)
dnl
dnl Test for the presence of a JDK, and (optionally) specific classes.
dnl
dnl If "JAVA" is defined in the environment, that will be the only
dnl java command tested.  Otherwise, a hard-coded list will be used.
dnl Similarly for "JAVAC".
dnl
dnl AX_JAVAC_AND_JAVA does not currently support testing for a particular
dnl Java version, testing for only one of "java" and "javac", or
dnl compiling or running user-provided Java code.
dnl
dnl After AX_JAVAC_AND_JAVA runs, the shell variables "success" and
dnl "ax_javac_and_java" are set to "yes" or "no", and "JAVAC" and
dnl "JAVA" are set to the appropriate commands.
dnl
dnl AX_CHECK_JAVA_CLASS must be run after AX_JAVAC_AND_JAVA.
dnl It tests for the presence of a class based on a fully-qualified name.
dnl It sets the shell variable "success" to "yes" or "no".
