Bad version number inside .class file #52

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1.Install SpringSource Tool Suite v2.x
2.Add Hudson Eclipse Plugin update site
3.Install v1.0.8 of the plugin
4. Add Hudon view to workspace

What is the expected output? What do you see instead?
Should see the hudson view with no errors. Instead see error message and
stack trace "bad version number inside .class file"

What version of the product are you using? On what operating system?
v1.0.8, Win XP, java version "1.6.0_15", Java(TM) SE Runtime Environment
(build 1.6.0_15-b03), Java HotSpot(TM) Client VM (build 14.1-b02, mixed
mode, sharing)

Please provide any additional information below.
Have had to roll back to v.1.0.7, but my colleague who has installed
vanilla cannot use the hudson plugin via install via the update site.

SOLVED: Tried with Java 6 and it worked as expected :-)
