Provide more detailed error when class org.jvnet.winp.Native could not be initialized

[segrey]

Sometimes return new WinProcess(myProcess).sendCtrlC(); fails with with the following exception:

The exception was received automatically from a WebStorm instance. It's also known that OS is Windows 10.
Unfortunately, there is no "caused by" linked exception making it impossible to figure out the cause.
Is it possible to enhance thrown exception?

Any chance to get more info, maybe there is some stacktrace below.
IIUC static initializer fails in https://github.com/kohsuke/winp/blob/master/src/main/java/org/jvnet/winp/Native.java#L93-L96 (CC @stephanreiter)

Just in case, which Java version do you use?

Actually, the error was thrown for one of our customers, it's not reproduced for me. All information we got in the automatic error report is:
IDE version: WebStorm 183.2635.17 (WebStorm 2018.3 EAP)
Java: 1.8.0_152 patched by JetBrains. It's bundled with the WebStorm.

This WebStorm build uses winp-1.27. If needed, here is the usage of winp in KillableProcessHandler.java.

Nope, no stacktrace below, unfortunately, thus the issue.

A possible fix could be to convert org.jvnet.winp.Native#ctrlCExePath to Future<String>. Then, each ctrlCExePath.get() will raise an exception or provide a value.
Or Exception object could be stored manually and re-thrown on each access.

Or Exception object could be stored manually and re-thrown on each access.

Maybe this one is preferable in this case.
At least we need to wrap it into WinpException so that errors get propagated to API users

@oleg-nenashev Yeap, looks good. Oh, I was wrong, it should better be Throwable, not Exception. ;)
