Package: openjdk-6-jdk
Version: 6b11-9.1+lenny2
Severity: normal
File: /usr/lib/jvm/java-6-openjdk/bin/javac
Specifically, compiling with -source 1.5 does not produce class files
compatible with a 1.5 jvm. Compiling with -target 1.5 does.
>From javac(1): "The default for -target depends on the value of -source:
[...] For all other values of -source, the value of -target is the value
of -source."
Reproduction steps:
$ javac -source 1.5 HelloWorld.java
$ javap -verbose HelloWorld | fgrep 'major version:'
major version: 50
$ javac -target 1.5 HelloWorld.java
$ javap -verbose HelloWorld | fgrep 'major version:'
major version: 49
>From the documentation, (and apparently from the Java Specification, but I
haven't looked that up personally), we would expect both compilations to
produce class files with major version 49.
