Hi,
Do you mind posting the output you get (only the compiler related
output is relevant) when specifying
printCompilerPropertiesVerbose=true ?
It doesn't give any output on my machine (only gives the errors
related to building tests) though printCompilerProperties=true still
gives the same output.
That's strange.
Here's what I get on a Windows machine I tested this on:
$ ant -DprintCompilerPropertiesVerbose=true

I don't remember exactly when this property was added, but it has been
in there for a while now. I tested on trunk revision 1050000.
Derby did pick the wrong JDK earlier, but work was done to avoid that.
If it still picks a JDK it can't use, it seems we may need further
improvements to this logic.

Note the addition of "Verbose" to the property string you used
previously. With this property set, you should get a list of all
JVMs the build system detects, and it also prints some basic
information about each of them.
It may help us understand why gjc is chosen, and if we have to
take action to avoid that the build fails when gjc is installed.
Also, was gjc installed by default on your machine?
No it wasn't preinstalled. It was installed as a dependency.
Thanks,

When you have learned to snatch the error code from the trap frame, it
will be time for you to leave.
