Error at breakpoint

[Ken]

I encounter an error when the debugger arrives at a breakpoint. I am
debugging by attaching to a running instance. I'm running JSwat from
the 4.5 binary. I believe I have followed the installation
instructions and readme properly. I tried removing my ~/.jswat
directory, but still receive the error.

Below is the message.log. Please let me know if I can provide more
information.

Thanks,
Ken

Hi,
looks like a netbeans thing
is this useful?
http://www.google.com/search?q=WARNING%3A+LibraryDeclarationHandlerImpl%3A+Cannot+create+library%3A+javac-+api+of+unknown+type%3A+j2se

maybe a netbeans installation problem?

Cheers,
John

Hi Ken

Sorry about that NPE, it was discovered earlier this year and fixed in
the source tree but a release has yet to be made. I want to make a new
release based on the NetBeans 6.7 platform but there are yet more
issues to be resolved in order to make that happen.

I believe the problem occurs when there is a path in either the
sourcepath or classpath that cannot be accessed by the JVM (maybe it
doesn't exist?). Look for anything in the sourcepath that you cannot
find on disk and remove it.

As for the problem John commented on, I do believe it's an issue in
NetBeans. I've tried to figure out a way around it but it's not
obvious.

Thanks

n

Nathan and John, thanks for your responses. The problem was inability
to find the .java source, which is in a separate tree.

I tried to help myself by building the 4.5 source. I'm not a NetBeans
user, so I installed 6.5 as directed. I was unable to build within the
IDE or from ant due to the following error. Is there a workaround?

BUILD FAILED

That probably happens because I updated the dependencies after
updating my installation of the NetBeans IDE. That is, at one point I
installed NB 6.5 and updated JSwat's source code. Then I updated the
IDE (e.g. 6.5 plus patches) and some of its modules were updated with
new version numbers. As a result I had to update the JSwat module
dependencies again.

So try checking for updates to NetBeans by opening the Tools menu,
selecting Plugins, and opening the Updates tab. If anything is there,
install them. If not, let me know and I'll see what can be done about
this.
