*
* @param requestor org.eclipse.jdt.internal.compiler.api.ICompilerRequestor

* Factory used inside the compiler to create problem descriptors. It allows the

* order to avoid object conversions. Note that the factory is not supposed
* to accumulate the created problems, the compiler will gather them all and hand
* them back as part of the compilation unit result.
