This issue occurs mainly when compiling LM-X SDK on multiple platforms. To resolve this problem, be sure to reuse the LM-X security configuration file.
Problem with JAVA_HOME environment variable
If building the LM-X SDK under Java fails, your JAVA_HOME environment variable is set to the JRE rather than the JDK, or it is set to a JDK that is not officially provided by Oracle.
If JAVA_HOME is not set properly, an appropriate warning message will be printed out while building LM-X, and LM-X will be built without Java programming language support.
To fix this problem, make sure your environment variable is set to the path of version 1.6 or newer of the JDK.
