javac2 7.0.3 fails when using -target 1.6

Hello Boaz,

Please file a JIRA issue - the javac2 task currently does not handle extdirs.
Loading classes is required in order to get correct frames information for
the new Java 6 bytecode verifier - the javac2 task from IDEA 6 didn't do
that, and it's also not done when using target 1.5.

Hi All.
Till now we works with javac2 taken from IntelliJ 6.
These days we are trying to move to javac2 that is distributed with
IntelliJ 7.0.3. (some important bug fixes in 7.0.3)
The jars we take from 7.0.3 are:
a.. forms_rt.jar
b.. jgoodies-forms.jar
c.. asm.jar
d.. asm-commons.jar
e.. javac2.jar
f.. jdom.jar
After some problems and with your help we replace asm.jar &
asm-commons.jar with latest version from http://asm.objectweb.org
Now we got this new problem that some class is not found. I want to
emphasis that beside the changes mention above no change was made and
it worked fine when using javac2 taken from IntelliJ 6.

The exception we got is:

Adding @NotNull assertions to
C:\Temp\maketmp\69700\class\wf\tool\application\alignment\solver\Abstr
actSolver.class
targetVersion: 1.6

Same thing happens for other classes. The common thing for all
problematic classes is that they are not under classpath but under
extdirs options, you can see the line

in the build script below:

<javac2 destdir="C:\Temp\maketmp\67656\class"
sourcepath="" srcdir="C:\views\BoazMainWF2_s\Q"
debug="true" nowarn="true"
memorymaximumsize="1024m"
fork="true"
executable="C:\views\BoazMainWF2_s\Qsnap\JDK\bin\javac.exe"
source="1.5"
target="1.6"

classpath="C:\views\BoazMainWF2_s\Qsnap\Qbuild\class;C:\views\BoazMain
WF2_s\Qsnap\Qrelease\jar\LowSysUtils.jar;C:\views\BoazMainWF2_s\Qsnap\
Qrelease\jar\RMASetup.jar;C:\views\BoazMainWF2_s\Qsnap\Qrelease\JarExt
\pbtools57.jar;C:\views\BoazMainWF2_s\Qsnap\Qrelease\JarExt\pbembedded
57.jar;C:\views\BoazMainWF2_s\Qsnap\Qrelease\JarExt\ImgrRdr.jar;C:\vie
ws\BoazMainWF2_s\Qsnap\Qrelease\JarExt\comm.jar"

extdirs="C:\views\BoazMainWF2_s\Qsnap\JDK\jre\lib;C:\views\BoazMainWF2
s\Qsnap\JDK\jre\lib\ext;C:\views\BoazMainWF2s\Qsnap\Qrelease\JavaExt
"

bootclasspath="C:\views\BoazMainWF2_s\Qsnap\JDK\JRE\lib\rt.jar"
includes= <omitted ...>
listfiles="false"
includeAntRuntime="no"
<compilerarg line=" "/>
</javac2>
Another and last thing, If I change javac target to be 1.5 then every
thing works fine.

Please your advise.

B.R
Boaz
