ANT builds fail on NB11.3 and 12.0

[xxxajk]

Describe the bug
Try to build an ANT project, and fail.
Note that ant debug works from shell.

To Reproduce
Steps to reproduce the behaviour:

1. Try to debug build the project
2. java.lang.InternalError: Could not obtain X500Principal access

android-sdk-linux build-tools 23.0.2
android sdklib.jar patched to not depend on Oracle's base64 implementation.

Product Version: Apache NetBeans IDE 12.0
Updates: NetBeans IDE is updated to version NetBeans 8.2 Patch 2
Java: 11.0.8; OpenJDK 64-Bit Server VM 11.0.8+10-post-Ubuntu-0ubuntu118.04.1
Runtime: OpenJDK Runtime Environment 11.0.8+10-post-Ubuntu-0ubuntu118.04.1
System: Linux version 5.4.0-42-generic running on amd64; UTF-8; en_US (nb)

I've found that there needs to be a couple of settings.
One such setting would be to select the system apache ant, instead of the ant plugin.
This would be an option much like available from the Java plugin.

So... is this project even still alive?

It's alive if you want it to be. Will you make those changes?

I'm still investigating the root cause. What is strange is that when I do:
ant debug
from shell, it is happy, no problems. Of course this is using the system ant...

I compared the output of each, and the messages from both are identical, except for the signing phase, which is failing.
I'm thinking here that the solution would be to fork and run ant, which is shell, instead of calling the class.

I've not fully checked, but it looks like even java compiles do the same thing on NetBeans.

Checked using the NetBeans supplied ant, works from command line too.
I think the solution here is to run ant from a login shell, or similar...

[xxxajk]

Looks like it is the fault of how the ant plug-in launches ant!
I've noticed a few changes from the older NBANDROID, of which I think the most important is:

Old NBANDROID would ask for the passphrase for the signing keys.

This could be the fix.

And... I located the big difference why it bombs.

Please note, I merged the needed jar files in my sdklib.jar long ago, so I could actually compile from the cli...

cli does this:

Finding class com.android.sdklib.internal.build.SignedJarBuilder$SignatureOutputStream

and everything is fine. Here's what netbeans tries to do:

Finding class com.android.sdklib.internal.build.SignedJarBuilder$SignatureOutputStream

Class sun.security.pkcs.SignerInfo loaded from parent loader (parentFirst)
Class sun.security.x509.X500Name loaded from parent loader (parentFirst)

and bombs :-)

So... it's not seeing javax or a different javax is already loaded into the parent class loader, thus no javax.security.auth.x500.X500Principal which would read in the remaining bits.
