# We have applied a patch to fix this version under Java 8. Trouble

|
# is that we need to run a prebuilt version before we can build our
|
| 72 |
|
# own and that version doesn't have the fix applied. We work around
|
| 73 |
|
# this by building just the offending class against the prebuilt
|
| 74 |
|
# version and then putting them together in the classpath. That
|
| 75 |
|
# isn't all. Due to a compiler limitation that Chewi doesn't fully
|
| 76 |
|
# understand, this class cannot be compiled by itself without a
|
| 77 |
|
# couple of tweaks that have been applied in the Java 8 patch.
