CHECK statement delete spaces

[meskio]

The CHECK statement seems to remove the spaces from the commands. Using the example https://github.com/radare/acr/blob/master/examples/check.acr it produces:

echo"importjava.util.*;">temp.java ;echo"classtemp{publicstaticvoidmain(){Vector<String>v=null;}}">>temp.java ;${JAVAC}-source1.5temp.java>/dev/null2>&1 ;JAVA5=$? ;rm-ftemp.java

Which fails as echoimportjava.uitl.*...: not found.
