Yes it will be.
What project is that ? Late night testing of JBoss Tools development releases ? :)
Only a small webshop. Therefore, we're considering Eclipse 3.4 & JBossTools 3.0 & JBossAS 4.2 vs. Eclipse 3.5 & JBossTools 3.1 & JBossAS 5.1
ah okey - I would definitively go for Eclipse 3.5 + JBossTools 3.1 + (JBoss 5.1 or JBoss 4.2).
Too many good fixes in eclipse base and jboss tools to miss ;)
