Javadoc plugin fails when -J-fullversion returns localized version string
-------------------------------------------------------------------------
Key: MJAVADOC-152
URL: http://jira.codehaus.org/browse/MJAVADOC-152
Project: Maven 2.x Javadoc Plugin
Issue Type: Bug
Affects Versions: 2.2
Environment: FreeBSD
Reporter: Matt Whitlock
Attachments: AbstractJavadocMojo.java.patch
On Mac OS X:
$ javadoc -J-fullversion
java full version "1.5.0_07-164"
On FreeBSD:
> javadoc -J-fullversion
java full version "diablo-1.5.0-b01"
The difference causes this exception:
java.lang.NumberFormatException: For input string: "dial"
at
sun.misc.FloatingDecimal.readJavaFormatString(FloatingDecimal.java:1224)
at java.lang.Float.parseFloat(Float.java:394)
at
org.apache.maven.plugin.javadoc.AbstractJavadocMojo.getJavadocVersion(AbstractJavadocMojo.java:2966)
...
See attached patch for a more robust way of parsing the output from 'javadoc
-J-fullversion'.
Do note that both the original code and the patched code will have problems
with Java versions like 1.10.0 or 1.6.10. The original code will fail with an
exception, while the patched code will return a somewhat nonsensical value from
the getJavadocVersion method. The Java version logically should not be
expressed as a float because semantically it is not a floating-point number but
rather an integer vector. A more appropriate return type for the
getJavadocVersion method would be int[].
