Minor Description
- EmailServices.java:547, REC_CATCH_EXCEPTION
REC: Exception is caught when Exception is not thrown in org.apache.ofbiz.common.email.EmailServices.sendMailFromScreen(DispatchContext, Map)
This method uses a try-catch block that catches Exception objects, but Exception is not thrown within the try block, and RuntimeException is not explicitly caught. It is a common bug pattern to say try
{ ... } catch (Exception e) { something } as a shorthand for catching a number of types of exception each of whose catch blocks is identical, but this construct also accidentally catches RuntimeException as well, masking potential bugs.A better approach is to either explicitly catch the specific exceptions that are thrown, or to explicitly catch RuntimeException exception, rethrow it, and then catch all non-Runtime Exceptions, as shown below:
try { ... } catch (RuntimeException e) { throw e; } catch (Exception e) { ... deal with all non-runtime exceptions ... }
- EmailServices.java:592, BX_UNBOXING_IMMEDIATELY_REBOXED
Bx: Boxed value is unboxed and then immediately reboxed in org.apache.ofbiz.common.email.EmailServices.sendMailFromScreen(DispatchContext, Map)
A boxed value is unboxed and then immediately reboxed.
- EmailServices.java:662, UC_USELESS_OBJECT
Useless object created
Our analysis shows that this object is useless. It's created and modified, but its value never go outside of the method or produce any side-effect. Either there is a mistake and object was intended to be used or it can be removed.
This analysis rarely produces false-positives. Common false-positive cases include:
- This object used to implicitly throw some obscure exception.
- This object used as a stub to generalize the code.
- This object used to hold strong references to weak/soft-referenced objects.
- EmailServices.java:715, EI_EXPOSE_REP2
EI2: new org.apache.ofbiz.common.email.EmailServices$ByteArrayDataSource(byte[], String) may expose internal representation by storing an externally mutable object into EmailServices$ByteArrayDataSource.contentArray
This code stores a reference to an externally mutable object into the internal representation of the object. If instances are accessed by untrusted code, and unchecked changes to the mutable object would compromise security or other important properties, you will need to do something different. Storing a copy of the object is better approach in many situations.
