[cross-project-issues-dev] JarProcessor and Java versions

[Thomas Hallgren <thomas@xxxxxxx>]

Hi,
I'm wondering if there are some options that can be passed to the 
Eclipse jarProcessor that will restrict the pack200 to a certain target 
level. My objective is to restrict builds to a certain target level 
(Java 1.5) regardless of what JVM that is used for the build. The build 
uses the ant task 'eclipse.jarProcessor'

At present, a machine running Java 1.5 will fail with the following on 
the top of the stack:

Stack Trace:
java.io.IOException: Corrupted pack file: magic/ver = CAFED00D/160.1 
should be CAFED00D/150.7
