c:\users\test\workspace\samplejava>java -version java version "1.6.0_45" java(tm) se runtime environment (build 1.6.0_45-b06) java hotspot(tm) client vm (build 20.45-b01, mixed mode, sharing)

c:\users\test\workspace\samplejava>javac -version javac 1.6.0_45

os: windows 7

had same problem - appears caused jdk being installed in folder space in path, i.e., "program files" - moved jdk installation c:\jdk , problem went away.
