Problems with multiproject and java 1.5 (LVT error)

[Johan Gorter <jg...@sogyo.nl>]

Hello all,

I have got an interesting problem that I am stuck on. My project uses
multiproject and java 1.5. When I use maven to test one of my subprojects,
everything works fine, all java 1.5 code compiles ok and the unit-tests run
ok.

When the multiproject plugin runs the unit-tests I get ClassFormatErrors.
This is weird, because the same classes ran and compiled ok when not using
multiproject. Multiproject even runs the files that were compiled and ran by
maven before. The class files are therefore not corrupt in any way.

Here is the output from running test:test :

Note that only BankTest accesses classes that use Java1.5 generics

Now multiproject output: (only relevant fragments)
