JDev 1013 Error: Internal compilation error, terminated with a fatal except

Question

I've a class I compiled used in JDev 10.1.2.1.
Now I try to compile it with JDev 10.1.3 but I get an error :
Error: Internal compilation error, terminated with a fatal exception
What does it means ?
How can I solve it ?
I tried to use both 5.0 and 1.4.2 compilers but the result is the same.
Tks

Answer 1

I setted use Javac checkbox and it worked ???
Could someone explain me what happened ?
The problem seems to be in the very long privated final string I defined, making it shorther the problem is solved again .
Tks
