Application cannot be started with JDK 13 - AWTSecurityManager was removed

Application cannot be started with JDK 13.

It throws exception:

Exception in thread "main" java.lang.NoClassDefFoundError: sun/awt/AWTSecurityManager

AWTSecurityManager was removed in 13, but is used in JNLPSecurityManager.

1. extend JNLPSecurityManager from SecurityManager instead of AWTSecurityManager
2. remove method getAppContext() from JNLPSecurityManager

Hi,
Today I patched my icedtea-web 1.8 branch (up-to-date) with the assocated patch #438 to get rid of the AWTSecurityManager class use.

It makes ITW 1.8 work on OpenJDK 13 to 17, tested on 15, 16, 17 EA.

I wonder if this fix could be backported to the iced-tea-web 1.8 branch to make it available in the coming 1.8.x release (for most linux users) as 2.0.x is still not publicly released.

Thanks,
Laurent

@sclassen see the pull request #792
It is the same patch as #438

If someone still has this issue I recommend to look on my workaround described here - https://github.com/egorsmkv/kvm-over-ip-cn8000a-jnlp-client
