[jcifs] Unable to create new native thread

[Michael Schlegel]

I made a update from jcifs-1.2.17 to jcifs-1.2.24 and now i get following
exception: 

java.lang.OutOfMemoryError: unable to create new native thread

In our code we check a big list of files if they exists or not.
The code lokks similar like this:

while( (nextFileToCheck = getNext() ) != null )
{
    if( nextFileToCheck.exists() )
    {
        //do something
    }
    else
    {
        //do something
    }
}
