I did a few tests to find out.  I have some code that gives the verifier
error I mentioned when doing a native compile with gcj 4.0.  I made up a
simple test case that used this class, and then found some machines with
JDK 1.4 and 1.5 on.

With the original 1.5 compiled class file (ecj -1.5), JDK 1.4 complains
about the version number without even examining any further into the
contents.

I then edited the class file to use the 1.4 version number, 48, in order
to simulate a 1.4 class file with ldc .class constructs.
With 1.4, the compiler fails:

Exception in thread "main" java.lang.VerifyError: (class:
nongnu/cashews/eclipse/composer/ui/PaletteFactory, method:
createComponentsDrawer signature:
()Lorg/eclipse/gef/palette/PaletteContainer;) Illegal type in constant
pool

The same thing occurs with a 1.4 class file on 1.5.  With the original
class file, the test runs.  So, it appears they follow the pedantic
approach.
