The report having put around 745 applications by 160 companies under the scanner for security, performance, changeability, transferability, uptime etc. in quantitative terms, has pinpointed some lacunae in Java due its to low performance scores. Having examined about 340 Java applications along with other technologies such as C++, Oracle, .Net, VB etc. The report has also pointed out the high cost ($5/ code line for Java against $3.6 for other competing technologies), security realm, interaction with server and mainframe based apps etc. in which Java appears to have scored low.
