Java Module Release Notes - Mule 4

Removed dependencies included in the Mule runtime engine to avoid warning messages during startup (JM-34)

Upgraded Spring version to 5.3.0 (JM-31)

Wrong OutputType for a method that returns a java.lang.Object type. (JM-14)

MUnit tests for metadata validation. (MU-1529)

Upgrade mule-extensions-parent, mule-core-modules-parent and mule-ee-core-modules-parent to 1.1.6. (MULE-17121)

Upgrade MUnit version to 2.2.1. (MULE-17301)

Change execution pool to CPU_LITE for new instance operations. (MULE-17326)

Change execution pool to IO for invoke operations. (MULE-17329)

Java module fails to invoke method that receives Optional<Pojo> (MULE-16932)

Java module fails to transform null into an empty Optional. (MULE-16918)

Upgrade Spring to 5.1.6.

Upgrade Apache Commons Lang to 3.8.1.

Fixed an issue with invoking a method from a class that implements an interface with generics. This would produce a warning that there were multiple methods found that match the provided method.

JavaModule: no longer throws WARN messages with Generic interface implementation. (MULE-16316)

It’s now possible to configure the Output MimeType of the Invoke and Invoke Static Operations.

Improved error handling, the connector used to not show the real error that occurred when executing Java methods.

New functions getRootCause and isCausedBy are now available to introspect Throwables.

In the extreme case where two parameters have the same simple name, such as some.Pojo and other.Pojo the full qualifier name can be used to avoid issues.

JavaModule: Support output MimeType parameter for runtime inference. (MULE-15283)

Java Module: Improve Error cause propagation. (MULE-15540)

Java Module: does not propagate execution error. (MULE-15262)

Java Module invokeStatic declares an error that is never thrown. (MULE-15461)

JavaModule: Support full qualifier name for parameter types to identify methods. (MULE-15009)

Migrate JavaModule tests to MTF. (MULE-15076)

Java Module: improve method not found error message. (MULE-15263)

Java Module: 'new' operation does not declare INVOCATION error. (MULE-15538)

Java Module: Fail to extract exception cause with default value. (MULE-15597)

Provide proper classloading error information. (MULE-14938)

Improve error messages and exception propagation. (MULE-15263)

Change execution pool to CPU_LITE for new instance operations. (MULE-17326)

Change execution pool to IO for invoke operations. (MULE-17329)

InvokeStatic declares an error that is never thrown. (MULE-15461)

Fixed an issue that made it impossible to pass null as a parameter.

Now when the arguments are passed by with their canonical name (arg0, arg1, etc.), parameter matching will be done by position.

JavaModule: Do best effort to do invocation with arg0, arg1…​ (MULE-15008)

null values causes Exception in parameterNeedsTransformation. (MULE-14990)

When argument types don’t match the java function arguments, a best effort will be done to transform these arguments.

Java module doesn’t transform the arguments. (MULE-14861)

Fixed an issue that happened when calling static methods from different classes with the same signature.

Invoke static second call wrong. (MULE-14785)
