[cbi-dev] WTP build failed to compile with latest Maven

WTP build works well with Maven 3.2.5. After moving to Maven 3.3.1, it failed to compile the plugin org.eclipse.wst.wsdl with the following error.
[ERROR] Failed to execute goal org.eclipse.tycho:tycho-compiler-plugin:0.20.0:compile (default-compile) on project org.eclipse.wst.wsdl: Compilation failure: Compilation failure:
[ERROR] /jobs/genie.webtools/WTP-R3_7_x_Maintenance_test/workspace/webtools.webservices/bundles/org.eclipse.wst.wsdl/src-wsdl/org/eclipse/wst/wsdl/util/WSDLParser.java:[787]
[ERROR] catch (IOException exception)
[ERROR] ^^^^^^^^^^^
[ERROR] Unreachable catch block for IOException. This exception is never thrown from the try statement body

It has been verified that the project can be compiled without a problem locally.
The following warning messages were found in the Maven 3.3.1 build log.

The following information was generated by Maven 3.2.5 build.

I wonder whether this has something to do with the toolchain. The BREE of the plugin is Bundle-RequiredExecutionEnvironment: J2SE-1.4 and the current toolchain is set up as the following.
<toolchains>
  <toolchain>
    <type>jdk</type>
    <provides>
      <id>J2SE-1.4</id>
    </provides>
    <configuration>
      <jdkHome>/shared/webtools/apps/IBMJava2-142-SR13FP10/jre</jdkHome>
    </configuration>
  </toolchain>
  <toolchain>
    <type>jdk</type>
    <provides>
      <id>J2SE-1.5</id>
    </provides>
    <configuration>
      <jdkHome>/shared/common/jdk-1.5.0-22.x86_64/jre</jdkHome>
    </configuration>
  </toolchain>
  <toolchain>
    <type>jdk</type>
    <provides>
      <id>JavaSE-1.6</id>
    </provides>
    <configuration>
      <jdkHome>/shared/common/jdk1.6.0_45/jre</jdkHome>
    </configuration>
  </toolchain>
  <toolchain>
    <type>jdk</type>
    <provides>
      <id>JavaSE-1.7</id>
    </provides>
    <configuration>
      <jdkHome>/shared/common/jdk1.7.0_25/jre</jdkHome>
    </configuration>
  </toolchain>

</toolchains>

I appreciate if someone can shed some light.

Best Regards
