Resolution

This error usually means that the Java installation in your PATH environment variable is not a JDK. 

Delphix does provide a JDK with the Delphix toolkit. 

To use the provided JDK with the hostchecker, refer to the following example:

-bash-3.2$ cd <your toolkit directory>
-bash-3.2$ find . -name javac
./Delphix_COMMON_564d5bfd_187c_ff17_14af_7e77caead436_sybase_host/java/jdk/bin/javac
-bash-3.2$ export PATH=${PWD}/Delphix_COMMON_564d5bfd_187c_ff17_14af_7e77caead436_sybase_host/java/jdk/bin:${PATH}
-bash-3.2$ which javac
/export/home/sybase/toolkit/Delphix_COMMON_564d5bfd_187c_ff17_14af_7e77caead436_sybase_host/java/jdk/bin/javac
-bash-3.2$ java -jar hostchecker.jar
