> Key: HARMONY-2558

> Project: Harmony
> Issue Type: Bug
> Components: DRLVM
> Reporter: Vladimir Beliaev

> According to JVMS for 'new' bytecode:
> http://java.sun.com/docs/books/vmspec/2nd-edition/html/Instructions2.doc10.html#new
> ... named class, array, or interface type is resolved (§5.4.3.1) ...
> ... On successful resolution of the class, it is initialized (§5.5) if it has not already been initialized....
> See also 5.5 Initialization (http://java.sun.com/docs/books/vmspec/2nd-edition/html/ConstantPool.doc.html#77976).
> ... A class or interface may be initialized only as a result of:
> o The execution of any one of the Java virtual machine instructions new, getstatic,...
> So, executing 'new' bytecode must cause a class initialization (in particlar <clinit> call). The attached test shows it is not true for recent version of DRLVM. In this test the <clinit> produce exception which is supposed to be catched in 'main' method.
> The issue is not reproducible with interpreter (-Xint) - marking this bug as JIT one.
> To prepare the test please build attached Jasm_part.jj first; then build Test.java.
> Test output is:
