rJava inside packrat

[wolkym]

rJava inside packrat has wierd behaviour.

If I launch rJava from a packrat repo, in the first run in throws exception, but on the second run works perfectly.

Do you have any ideas how that can happen?

I have created issue in rJava repo

Presumedly, the RJavaTools class files are distributed as part of the rJava package. Are they present there?

What's the output of:

javaPath <- system.file("java", package = "rJava")
list.files(javaPath)

in each case?
