If you break the running DataBasic Object code you will see the code that the hang relates to e.g.
Execution break: Program Name line_number
line_number > %import(parameter)
In order to resolve the hang you need to reinstall the Reality Java Language Server.
Once re-installation is complete, any third party jar files will also need to be re-installed.
The new location for the libraries is displayed when the installation of the Reality Java Language Server is completed.
Note: You must restart the RealJLS server after installing new jar files.
Examples:
On Windows, the re-installation ends displaying:
Your JAVA_HOME folder is C:\Program Files\Java\jdk1.8.0_05
and third party jar files should be installed in
C:\Program Files\Java\jdk1.8.0_05\lib\ext
On UNIX:
Each incremental update to Java moves the directory structure, so the re-install has to be done more frequently.
