/**
|
|
* Adapted from xpcom/tests/TestArray.cpp
|
|
*
|
|
* This tests the following parts of the Java<->XPCOM code:
|
|
* - Creating an XPCOM object in Java, and calling its methods.
|
|
* - Calling several of the Gecko embedding funtions.
|
|
* - Passing Java class objects to XPCOM.
|
|
* - Have XPCOM call Java class' queryInterface() method.
|
|
* - Catching GeckoException.
|
|
* - Lifetime of JNI structures and Java objects (everything should be
|
|
* garbage collected or destroyed at the appropriate time).
|
|
*
|
|
* NOTE: The System.gc() calls throughout the testcase are used to tell the
|
|
* JVM that now would be a good time to garbage collect. This helps us see
|
|
* if everything is getting freed properly. However, since the System.gc()
|
|
* call is only a suggestion to the JVM (you can't force garbage collection),
|
|
* this testcase may not work the same on every system. On my system, it
|
|
* usually works as expected (that is, Java objects that are no longer in
|
|
* use are destroyed whenever System.gc() is called). But I have seen some
|
|
* instances where the garbage collector ran later in the testcase.
