Invalid java.io.tmpdir will cause NullPointerException in static initializer which leads to ExceptionInInitializerError #46

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Set system property java.io.tmpdir to a directory which does not exist
2. Run proxy-vole on Windows with the Browser Strategy
3. => Exception occurs because the result from File.listFiles() in 
DLLManager.cleanupTempFiles() is not checked for null, but is invoked via 
static initializer in Win32ProxyUtils:

java.lang.ExceptionInInitializerError

What is the expected output? What do you see instead?
* Proxy vole detects browser settings and does not throw Exceptions

Hi
I added some null checks and catch all errors that occure during cleanup.
This is fixed with revision 116. 

This will be included in the next release that will come this week.
