Since I totally fail to work around, I would really appreciate some help.
This is how the original (before I started to work around) block looks like:
java_home_guess="`java -verbose 2>&1 | sed -e 's:^\[[^]/]*\(/.*\)/[^/]*\.jar[]
].*$:\1:' -e t -e d | sed -e 's:/[Cc]lasses$::' -e 's:/lib$::' -e 1q`"
The problem is with this line which has an unbalanced bracket. All
you need is to balance it, i.e., I'd propose
AC_MSG_CHECKING(for JAVA_HOME)
AC_CACHE_VAL(pike_cv_java_java_home, [[
if test "x$JAVA_HOME" = x; then
pike_cv_java_java_home=no
# We need balanced brackets: [
java_home_guess=`java -verbose 2>&1 |
sed -e 's:^\[[^]/]*\(/.*\)/[^/]*\.jar[] ].*$:\1:' -e t -e d |
sed -e 's:/[Cc]lasses$::' -e 's:/lib$::' -e 1q`
for tmp_java_home in /usr/java /usr/local/java /usr/local/jdk* /usr/java*/jre
/usr/java/jdk*/jre /usr/local/java*/jre /usr/local/jdk*/jre /usr/local/jre*
"$java_home_guess" "$pike_java_user_lib_directory"/..; do
if test -d $tmp_java_home/.; then
if ls
"$tmp_java_home/lib/$pike_cv_java_arch/$pike_cv_java_threads_type"/libjvm* >/dev/null
2>&1 || \
ls "$tmp_java_home/lib/$pike_cv_java_arch"/libjvm* >/dev/null 2>&1 || \
ls "$tmp_java_home/lib/$pike_cv_java_arch"/classic/libjvm* >/dev/null 2>&1

ls "$tmp_java_home/bin"/classic/libjvm* >/dev/null 2>&1 || \
ls "$tmp_java_home/Libraries"/libjvm* >/dev/null 2>&1; then
pike_cv_java_java_home="$tmp_java_home"
else

fi

done
else
if test -d "$JAVA_HOME"/jre/lib; then
pike_cv_java_java_home="$JAVA_HOME"/jre
else
pike_cv_java_java_home="$JAVA_HOME"

fi
]])
AC_MSG_RESULT($pike_cv_java_java_home)
(see the comment) which is 2.13 and 2.50, otherwise you can use @:>@
to represent `]' with 2.50.
