Bug#445930: libgcj8-1: Problem to compile and to execute java Swing code
Package: libgcj8-1
Version: 4.2.1-5
Severity: important
Hi,
Since upgrading to the 4.2 version of gcc/gcj, I have errors for
programs that worked before (with 4.1). Maybe I do not have all the
packages installed?! Here are the errors:
1. Compilation error:
snoopy:~/smart-surface/simulator$ javac Main.java
Exception in thread "main" java.lang.NoClassDefFoundError:

2. Execution error:

[During execution, depending on the program, either all the interface
is shown, but no event is generated (the interface does not respond to
any click, key press), or the interface is not shown at all.]
I can attach the program, if needed.
