STM32CubeMx not working anymore after update from 5.4.0 to 5.5.0

[Katzenberger.Michael]

Hi !

After updating I'm not able to load any project or generating a new one.

Each time a project is loaded the program crashes with

...

Please see attached text file for full log.

problem is because of jave

please update java first then try

Thanks for your feedback.

But neither a update of java11 nor installing java13 solves the problem. I've attached the full log of both java versions.

you mean this comment, right ?

STM32CubeIDE toolchain:

• It is functional only with a Java 8 64-bit Java Virtual Machine.

I've used this java version in the past (and STM32CubeMX version 5.4.0 was running fine with that):

> java -version
openjdk version "1.8.0_232"
OpenJDK Runtime Environment (build 1.8.0_232-8u232-b09-0ubuntu1~18.04.1-b09)
OpenJDK 64-Bit Server VM (build 25.232-b09, mixed mode)

Although the revision number (?) is 232 I've downloaded the latest available package form java.com which has a revision number of 231

> java -version
java version "1.8.0_231"
Java(TM) SE Runtime Environment (build 1.8.0_231-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.231-b11, mixed mode)

Unfortunately no improvement ...

And the jdk version is not downloadable without an Oracle account.

So currently all installed versions didn't work:

> sudo update-alternatives --config java
There are 4 choices for the alternative java (providing /usr/bin/java).
 
  Selection    Path                                            Priority   Status

  2            /usr/lib/jvm/jdk-11/bin/java                     0         manual mode

* 4            /usr/lib/jvm/jre1.8.0_231/bin/java               0         manual mode

Finally a fresh install of STM32CubeMx solved the problem !

Hi Michael

What java version are you finally using?

[Katzenberger.Michael]

Hi Christian,

obviously the "only Java 8" statement is not true 😉

I'm running jdk-13

> java -version
openjdk version "13" 2019-09-17
OpenJDK Runtime Environment (build 13+33)
OpenJDK 64-Bit Server VM (build 13+33, mixed mode, sharing)

[Christian1]

Thanks for you answer

I have java 8 now and after a clean install of CubeMX 5.5.0, it actually works fine now

$ java -version
openjdk version "1.8.0_242"
OpenJDK Runtime Environment (build 1.8.0_242-8u242-b08-0ubuntu3~18.04-b08)
OpenJDK 64-Bit Server VM (build 25.242-b08, mixed mode)

(I had java 11 before and CubeMX 5.4.0 was working fine with it)
