[Swift-devel] Swift parser fails under Java 1.6.0_07

[Michael Wilde]

I (with the help of a new user) just painfully re-discoverd that Swift's parser fails under the (somewhat old) Java JRE release 1.6.0_07 which happens to be the default under on the UChicago IBI cluster.

[wilde at ibicluster t2]$ java -version
java version "1.6.0_07"
Java(TM) SE Runtime Environment (build 1.6.0_07-b06)
Java HotSpot(TM) 64-Bit Server VM (build 10.0-b23, mixed mode)

When I run under 1.6.0_20 the problem does not occur.

Under _07, Swift fails compiling even the most trivial script, as in the example below, in which I include the complete log file.

Has anyone else seen this, and/or know the cause?

Im puzzled that the swift .log file doesn't start with the typical version and environment info. Its almost like swift is taking some strangely different execution path under 1.6.0_07.

This is not yet a major issue, but its unsettling that a specific java version could trigger this behavior.
