Summary: java.lang.AssertionError
Initial Comment:
I am running Fedora Core 6 Zod and when I started Dr Java for the first time, it gave an error message saying that it cannot locate tools.jar. So when I managed to locate and install JDK 1.4.2, that error was replaced by another one which says:
An error occured in DrJava:
java.lang.AssertionError
You may wish to save all your work and restart DrJava.
When I click on More Information, I see a pane with error messages (attached below).
At present I have the following versions of the JDK:
j2sdk1.4.2_13
jdk1.5.0_10
jdk1.6.0
all in /usr/java (by default). In addition I have JRE 1.5.0_10 in /usr/java/jre1.5.0_10/.
The j2sdk1.4.2_13 was installed recently, after which the tools.jar error stopped popping up. But the other versions have been around for some time.
As I have stated above, I am unable to even start Dr Java on my system now. Please help.
Thanks and regards,
Vivek
[PS--The .jar file is not corrupted]
