public List<CardTerminal> javax.smartcardio.TerminalFactory.waitForCardPresent(List<CardTerminal> terminals, long timeout)
public List<CardTerminal> javax.smartcardio.TerminalFactory.waitForCardAbsent(List<CardTerminal> terminals, long timeout)

of RI does not throw IllegalArgumentException in case when terminals contains CardTerminals created by another factory.
Specification directly specifys this:
"Throws:
        IllegallArgumentException - if timeout is negative, if terminals is the empty list, or if one of the terminals were not created by this TerminalFactory
"

There is a minized test in attached test.zip. It contains sources of 2 providers and 2 dummy TerminalFactorySpi implementations, dummy implementations of CardTerminal, Card and CardChannel and main test.java source, there problem is shown.

unzip it in some empty directory, then compile java source by java 6.0 compiler:
javac *.java

then run the test:
java -cp ./ test

the output will be:
factory of 1st CardTerminal:TerminalFactory for type None from provider None
factory of 2nd CardTerminal:TerminalFactory for type JCKDummy1 from provider JSCIOTCKProvider1
IllegalArgumentException was not thrown as expected.
