JetUML launch inconsistencies for loading SequenceDiagram

[Laurieprince]

Description There are some inconsistencies in loading sequence diagrams in integration_3_5.

Steps to reproduce Scenario 1. Load large.sequence.jet

Launch Eclipse Launch JetUML Open large.sequence.jet Error “error_another_integer_null.txt” Stop JetUML Launch JetUML Open large.sequence.jet

• Diagram opens in JetUML
• Error "java.lang.NullPointerException: Cannot invoke "java.lang.Comparable.compareTo(Object)" because the return value of "java.util.function.Function.apply(Object)" is null" (error_apply_object_null.txt)

Stop JetUML Launch JetUML Open large.sequence.jet

• Diagram does not open in JetUML
• Error java.lang.NullPointerException: Cannot read field "value" because "anotherInteger" is null (error_another_integer_null.txt)

Stop JetUML Stop Eclipse

Scenario 2. Loading small.sequence.jet then large.sequence.jet

Launch Eclipse Launch JetUML Open small.sequence.jet No errors, Success Open large.sequence.jet No errors, Success Stop JetUML Launch JetUML Open large.sequence.jet

• Diagram does not open
• Error java.lang.NullPointerException: Cannot read field "value" because "anotherInteger" is null (error_another_integer_null.txt)

Stop JetUML Stop Eclipse

Scenario 3. Load constructor.sequence.jet

Launch Eclipse Launch JetUML Open constructor.sequence.jet

• Diagram does not open
• Error “Cannot invoke "java.lang.Integer.intValue()" because the return value of "java.util.Map.get(Object)" is null” (error_map_get_object_null.txt)

Stop JetUML Launch JetUML Load small.sequence.jet No errors, Success Load constructor.sequence.jet No errors, Success Stop Jetuml Stop Eclipse

Configuration

• JetUML Release: integration_3_5
• OS + version: Windows 10
