Updating properties file java
(188.8.131.52.0) onwards, you can upgrade the existing JDK to a newer version, and can have the complete product stack point to the newer version of the JDK.
For example when you would be using Eclipse, and the file is in a source folder, the modified file is in the (hidden) bin folder and not in your source folder. The get Resource() method looks relative to your classpath, whereas the file is written relative to the current directory.
