| Reproducing code:
OUTER:
while (true) {
for (OSProcess proc : ProcessTree.get()) {
if (proc.hasMatchingEnvVars(Collections.singletonMap("foo", "bar"))) {
break OUTER;
}
}
}
Analysis: 1. OSProcess#hasMatchingEnvVars assumes that OSProcess#getEnvironmentVariables never returns null (and its Javadoc says so). 2. There's a time frame between ProcessTree.get() and call to getEnvironmentVariables 3. If proccess exits during this timeframe, an exception is thrown by org.jvnet.winp.WinProcess#getEnvironmentVariables, propagated through WindowsOSProcess#getEnvironmentVariables2, then caught in WindowsOSProcess#getEnvironmentVariables 4. And finally, WindowsOSProcess#getEnvironmentVariables returns null, thus violating contract from superclass Javadoc. |
