Thank you for investigating the problem and your response. Obviously it’s not absolutely necessary to have folders starting with the dollar sign, though it’s my habit and I simply haven’t expected that to be the cause of this (or any) NPE.
From my point of view, any legal paths may as well be handled correctly.
Unfortunately renaming that folder doesn’t seem to work, even after renaming the folder and, in subsequent attempts, trying to start it from within the folder or moving the folder to a very short path with no objectionable characters in it, it still crashes:
<br />
c:tempvakkk>java -Xmx1024m -jar pd4ml.jar<br />
java.lang.NullPointerException<br />
at java.io.File.<init>(Unknown Source)<br />

at org.zefer.pd4ml.tools.PD4Browser.showGUI(Unknown Source)<br />
at org.zefer.pd4ml.tools.PD4Browser.main(Unknown Source)
which keeps puzzling me.
Now I was testing with the version 399fx1.
Could the issue be another one?
UPDATE: I have tested some more, tried to run other (older) JVMs and the exception seems to be the same with all of them:
