I have seen this behaviour a couple of times on Windows machines. My
workaround was to change some entries in the registry:
Start the registry editor, go to HKLM\Software\JavaSoft\Java Runtime
Environment. There you'll find subentries for the different JDKs you have
installed, at least two for each major version:
* 1.6 and 1.6.0_<version> for Java 6
* 1.7 and 1.7.0_<version> for Java 7
Each one contains properties "JavaHome" and "RuntimeLib". These normally
point to the plain JRE installation on your machine which doesn't contain
the Java compiler. Try to change them and let them point to the additional
JRE installation under your JDK installation directory. Example:
* JavaHome: C:\Program Files\Java\jdk1.6.0_31\jre
* RuntimeLib: C:\Program Files\Java\jdk1.6.0_31\jre\bin\client\jvm.dll
Then everything should work.
