c3p0 com.mchange.v2.lang.VersionUtils: java.version ''1.6.0_03-p4'' could not be parsed. Defaulting to JDK 1.1

saper, pt., 07/25/2008 - 17:02

When playing with JForum I have noticed a small annoyance in the log:

java.version ''1.6.0_03-p4'' could not be parsed. Defaulting to JDK 1.1

(This problem has also been reported on some Russian forum).

I have four JDK's installed on my machine:

FreeBSD JDK 1.5 compiled from source:

java version "1.5.0_13-p7"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_13-p7-root_03_dec_2007_00_10)
Java HotSpot(TM) 64-Bit Server VM (build 1.5.0_13-p7-root_03_dec_2007_00_10, mixed mode)

Diablo FreeBSD JDK 1.5 binary:

java version "1.5.0"
Java(TM) 2 Runtime Environment, Standard Edition (build diablo-1.5.0-b01)
Java HotSpot(TM) 64-Bit Server VM (build diablo-1.5.0_07-b01, mixed mode)

FreeBSD JDK 1.6 compiled from source:

java version "1.6.0_03-p4"
Java(TM) SE Runtime Environment (build 1.6.0_03-p4-saper_24_feb_2008_06_54-b00)
Java HotSpot(TM) 64-Bit Server VM (build 1.6.0_03-p4-saper_24_feb_2008_06_54-b00, mixed mode)

and the Linux Sun JDK 1.5 running under Linux ABI emulation for the FreeBSD:

java version "1.5.0_15"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_15-b04)
Java HotSpot(TM) Server VM (build 1.5.0_15-b04, mixed mode)

As the J2SE SDK/JRE Version String Naming Convention specification says, all non-FCS (First Customer Shipment) i.e. unofficial or patched builds should contain the identifier after a dash and it does not have to be numeric.

The FreeBSD port is using this to determine which Java2 patchset has been applied to the original source when compiling.

Therefore I would suggest a small patch to com.mchange.v2.lang.VersionUtils class (this one can be applied to the source code of c3p0 0.9.1.2 version):

And a small test case in Jython (don't forget to put the c3p0 jar file on your classpath):

for (v, expected) in [ ("1.3.0", [1, 3, 0]),

What's your java version string?

Can you provide your java version string?

Thanks Marcin, this small

Thanks Marcin, this small annoyance is giving me lots of headache.
