In the Windows build.bat script, command-line parameters are processed using the following code:

"%JAVA_HOME%\bin\java" -classpath "%CP%" org.apache.tools.ant.Main -buildfile build.xml %1 %2 %3 %4 %5 %6 %7 %8 %9

This limits the number of command-line parameters to 9, which is not sufficient for executing builds which make use of many system properties (e.g. in the QA lab).
