[NETBEANS-6027] IDE freezes when using Maven + "Xlint:strictfp"

• Type: Bug
• Status: Closed
• Priority: Major
• Resolution: Cannot Reproduce
• Affects Version/s: 12.4, 12.5
• Fix Version/s: ?

Environment

These are the versions of my software:

• OS: Debian GNU/Linux 10.10 (Buster).
• Java platform:

    openjdk version "17" 2021-09-14
    OpenJDK Runtime Environment (build 17+35-2724)
    OpenJDK 64-Bit Server VM (build 17+35-2724, mixed mode, sharing)
  

The JDK build has been downloaded directly from java.net.

I've also tested the IDE with JDK 16, using a build downloaded from Adoptium. But the result has been the same.

Description

Hello:

I'm developing a Java project using Maven. If I write this configuration in the pom.xml file:

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-compiler-plugin</artifactId>
  <version>3.8.1</version>
  <configuration>
    <release>17</release>
    <compilerArgs>
      <arg>-Xlint:all</arg>
    </compilerArgs>
   <showWarnings>true</showWarnings>
 </configuration>
</plugin>

And then, I edit any Java source file, the IDE freezes completely. I've to kill the process.

However, if I replace the "-Xlint:all" argument with this equivalent value:

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-compiler-plugin</artifactId>
  <version>3.8.1</version>
  <configuration>
    <release>17</release>
    <compilerArgs>
      <arg>-Xlint:cast,classfile,deprecation,
        dep-ann,divzero,empty,fallthrough,finally,options,
        overrides,path,processing,rawtypes,static,
        try,unchecked,varargs</arg>
    </compilerArgs>
   <showWarnings>true</showWarnings>
 </configuration>
</plugin>

It works well.

It also works well if I remove the compiler arguments all together.

There is a visual defect that indicates me whether the IDE is going to freeze or not before saving the file: The code that is after the text block partially loses its highlighting and becomes white. Please, check the attached screenshots.

UPDATE #1.

I've continued making tests, and I've realized that the value all in -Xlint:all is equivalent to more values than I thought:

auxiliaryclass
cast
classfile
deprecation
dep-ann
divzero
empty
exports
fallthrough
finally
missing-explicit-ctor
module
opens
options
overloads
overrides
path
processing
rawtypes
removal
requires-automatic
requires-transitive-automatic
serial
static
strictfp
synchronization
text-blocks
try
unchecked
varargs
preview

By removing one by one, I've found which one causes the freeze: strictfp .

UPDATE #2.

I confirm that the value text-blocks also causes the same problem if there is at least one text block in the source file that is currently open. The highlighting fails and I can't save the file.
