Description Martin Aeschlimann

2003-03-20 08:17:19 EST

20030319

- Add jre_1.4_1_SR3 to the JRE, set it to default (no source attached)
- Open a 'Applet', press the 'Attach Source'
- Set source attachment to 'src.zip' from either
  Sun JDK 1.4.0 Beta 3
or
  SUN jdk1.4.1_b14

The outliner starts flashing for several seconds, the log is filled with NPE's

I can reproduce it be setting the source attchment again to nothing, and 
opening the file & press 'Attach Source'

No problems when the 'Source attachment' property dialog is used.
