Problem occured with Ecplipse Elios running on Windows 7 System
Sometimes some eclipse project doesn't start while others does.
Not running projects launch this error message :
Exception occurred executing command line.Cannot run program "C:\Program Files\Java\jdk1.6.0_16\bin\javaw.exe" (in directory "C:\paolo_lavoro\rep_svn\branches\cm\br-dev-inem-cm-2.3\iEMX-GUI"): CreateProcess error=87, Parametro non corretto
That error reason is quite simple: CLASSPATH is too long ; perhaps you have too many project dependencies in not running projects while shorter projects dependencies in running projects.
One solution is keep all dependencies while compiling project and removing them while run classes.
